Is There A Dog Game Like Club Penguin

A quiet evening sky

9/12/2009. After long abstinence I finally managed to observe, albeit with a sky from 20:40 SQM usual site, the foothills of Verona. In the words of my motto: be content: even so I enjoyed it. Rose early, at 18 I was already operational and have observed up to 24 in astrophotographers company of three friends: an exchange of conversation, tea, curiosity, every now and then does not hurt. Load-unload, assemble-disassemble, recharge, disassemble a big dob it can be seen as an effort stressful if you do it reluctantly and in a hurry, or an exercise in Zen, if you do it quietly, enjoying the precision mechanics. Then he fits in, and prepare the eye and the laptop: the same speech. I arrived at the 91 ^ output e dico la verità che sto pensando ad un nuovo telaio ultraleggero e meccanicamente più semplice. Ma intanto proseguo il mio addestramento Zen. Ho in serbo una lista ai confini tra Pesci e Pegaso, un salto in Cassiopea e uno in Cefeo. Soprattutto galassie. Con questo inquinamento, vedremo.

Il gruppo di NGC 80

L’immagine è già invertita per l’osservazione in un newton. L’ 80 e l’83, due lenticolari, sono una facile preda. La coppia 91-93 emerge dopo un po’ ma è certa; anche la coppia 85-IC 1546 emerge in distolta; notare che both are credited to A greater integrated around 15.60! (But the surface brightness is reassuring: 23:50 * m ^{arcmin 2)} : a proof that the integrated magnitude tells us almost nothing about the visibility of deep sky objects. 86, 84 and 79 (to say nothing of other galaxies close) I will be too uncertain and requires confirmation under the best skies.

group 7619.7626 in Pegasus, on the border with Pisces.

The two main galaxies are easy. Just south-west of the small 7619 7617 is not easy but ben accessibile; la 7623 agevole, separata dalle iniziali da una stella che serve di guida. Su 7615 rimango in dubbio; la 7631 è debole ma accessibile; per la 7608 mah, non posso dire di averla percepita con certezza.

Cassiopeia:

irregular dwarf galaxy IC 10, a group of local, heavily obscured by dust in our Galaxy, although detectable ethereal, outside a triangle of stars which can be reached by following a chain of Beta Andromedae field stars. The image above is a field in a little 'less than half a degree (side)

Cepheus:

Sh2-136 (Sharpless), vdB149, 150, 152 (van den Bergh), the most interesting is that Sharpless has a fan shape, but I can not take in view under the sky, or make very in wide-field image, but very charming and informative text:

The others are smaller objects peristellari, barely perceptible, a little different in appearance from a ring of diffraction, reflection nebulae not improve with the filters. See:

Meanwhile, Orion has risen, so the monster astrophotographers some spectacular image of M42-43 and the Flame. Then come to observe an object that had me very intrigued, the planetary Abell 12. Elementary to find, Just point the Mu Orion O-III and mount that attenuates the brightness of the star, revealing the planet, a kind of budding!

The modest miracle of fog.

Nebbia in Val Padana ... was so a week: dense fog in the plains, the Alps, with clear skies. It 'an ideal situation, many times you want that this time it was made Saturday in a New Moon. Destination Visdende
Val. We wondered what on earth would have had a night without light pollution Serbian. The answer in the picture (click to enlarge).


left the position last month, to the south Right on Saturdays (you can see Sirius, M41, Orion). The light of last month comes from the Po Valley at 60-100 km (there is nothing in the South before). The fog blocked the light and dark as much as the South was the North. I explored all sides with the camera but not c'era nessun segno di IL. L'airglow era visibile in tutte le direzioni, anche se il profilo dei monti impediva di vedere fino all'orizzonte (che diventa nero quando c'è solo airglow).
Per vedere l'airglow la cosa migliore, come mi ha spiegato Mars4ever, è stare seduti guardando lo zenit e cercare di ampliare l'angolo di vista fino a vedere l'orizzonte tutto attorno. Si vede il cielo un po' come in una fotografia con fisheye, e l'airglow tutto attorno è evidente.
La Via Lattea attraversava tutto il cielo. La parte estiva era fortemente strutturata, più uniforme quella invernale. Con un po' di attenzione si potevano vedere diverse gradazioni della Via Lattea estendersi molto lontano dal piano galattico, anche nella parte winter. The sky was far from uniform in intensity. Apart from the Milky Way and the airglow, the Gegenshein was also evident as a pale zone in the Pleiades and to the west. Above and below the gegenshein the sky was darker. You could also see the Zodiacal Band, which started from Gegenshein and towards the Milky Way (which was confused with this) is more apparent, continued westward where the limits of perception. The zodiacal light was more intense in the east gradually rising and that part of the sky seemed to be "polluted" than the rest. The darkest area of \u200b\u200bthe sky was the north east, the Big Dipper. Sirius, when it emerged from the mountains to the south-east was so intense as to disturb the adaptation in the dark. The SQM

started from 21:54 (first reading), is a bit 'down as they passed some cloudiness, and then stabilized at 21:50 from 11.10 (average of many readings with three different instruments in an SQM-L) to arrive around 21:55 to 2:30 at night. These readings refer to the zenith (SQM is normal for L version). Pointing the darkest part of the wagon SQM-L showed a mean value of 21.65 (between 21.62 and 21.69).

The veils that have gone in the first part of the night was slightly illuminated from below, from light coming from Santo Stefano di Cadore and Comelico (which were not under the fog). But little do so much so that their brightness was still I put more of the sky.

At some point in the night I also did a walk along the road towards the woods. The trees stood out Nerissa on the sky, and the sky seemed much brighter than the black silhouettes of trees.

The question remains of why the sky was only "21:55, since it lacked any light pollution. The explanation, in the days after investigating the matter, is that the airglow is a phenomenon that exhibits some fluctuations in intensity of short-scale (due to gravity waves in the atmosphere), other seasonal scale and ultimately other scale of 11 years due to the solar cycle. Those pitches appear to be connected to alternating hot and cold, with autumn and the first inverno i periodi in cui il cielo naturale è più luminoso e la primavera fino all'estate inoltrata in cui il cielo è più buio.

E' quindi probabile che abbiamo osservato un cielo naturale, ma in un periodo di massimo airglow.

La Val Visdende è a quota relativamente bassa: 1300 metri. Per questo è mediamente più calda degli altri siti in quota. C'erano infatti solo 5 gradi sotto zero. Il contro è che c'è più aria sopra e quindi un po' più di estinzione. M33 era l'unica nota stonata: visibile in distolta con un po' di difficoltà (presumo forse a causa della estinzione).
Il seeing è stato buono nella prima parte della notte: le stelle erano puntiformi a 260x (anche thanks to the fan who has always worked). In the second part of the night is a bit 'worse.
Compared to this time last month we arranged a bit 'in the valley below, in practice after clearing the last: 46 ° 37'24 .60 "N 12 ° 37'37 .20" E. There were trunks of trees, evidently the work of the woodcutters. And there was the smell of resin to keep us company. A few cars every now and then come in and changed direction (after the valley is closed).

We observed a large quantity of the items. Do not list them all but the most significant.

PK 93-2.1 planetary is a small diamond shape. You could take the form, a bit 'as in picture but much more tenuous, at high magnification.
PK 86-81 is another planet that you could catch a bit 'structure always at high magnifications.
invisible elephant's trunk BSI 142. Instead, Barnard was a fine show 168 species using 32 mm at 57x. You could follow the entire strip to the dark side where it expands. On the other hand, the Cocoon was clearly visible (preferably with a 86x 21 mm) and showed different internal irregularities.
observed Abell 77 with OIII and UHC filters at 260X, but seemed to have a very weak internal less bright (typical aspects of his eyes as the Owl).
PN M 2 5 1. Also observed at this inrandimenti similar.
In the meantime I did the photos impossessao Marco had the telescope. Among the objects selected by pointing and Mark mention:
NGC7177, NGC 1201 (we take advantage of the horizon south of observing objects bass), NGC 1255 (this one could guess the spiral shape), NGC1360 (a large planetary nebula that was very evident, including internal irregularities in the medium magnification OIII.
1532 NGC1531, a nice pair of galaxies. Of the greater is sensed irregularities. The couple 2293 2292 . NGC 2280 . NGC925 .

An interesting comparison was Thor's helmet, 30 cm and 40 cm. This object 10 cm extra make a significant difference, showing intricate structures and the shape of the helmet with much more clarity.

Another worth mentioning was the nebula planetary M46. They saw two stars, and internal, for high magnification, a ring with the center hole.

observing the clouds ...

As you can tell from the title, the release yesterday of the Three Peaks was not lucky. Despite the weather we have been continuously washes and high clouds that moved from north to south Large portions of the sky were alternately usable.
The clouds bring out the light pollution over the plains and the valley de''Adige. When opening a bit 'the SQM began to rise. 21.3 if there was little clear sky, 21.4 if it was more. 21.2 If the South was covered with clouds that reflected the light from the plains ... 100 km away!
Some items, however, have seen better than in Val Visdende (when it was possible to take them through an area of \u200b\u200bsky free enough). NGC6946, for example, you could see better than the week before in Val Visdende, but nothing to do with the view of August. The
Gegenshein we have seen perhaps a bit 'better. The seeing was poor, perhaps as a result of the currents. The temperature was above zero to three (unusual) and there were also several abrupt changes in the night.
Also notable is the view of Via Lattea invernale, per quel lasso di tempo in cui si è potuta vedere pulita.
I poveri malcapitati (io, mars4ever, mirko, radames e andreaf, hanno salvato il salvabile, armeggiando con un totale di 148 cm di apertura: due 40, due 30 e un rifrattorino da 8 cm... senza contare i binocoli).
Abbiamo dormito all'hotel "La Montanina" ad Auronzo. 40 euro per cena, pernottamento e prima colazione.

La mia lista di oggetti:
NGC 7309. Piccola galassia con le spirali invisibili.
NGC 7727. Si vedeva il nucleo e si intuiva l'alone.
M 74. OK, qua ci ho speso più tempo. L'estensione della galassia era visibile, ma difficile vedere le spirali.
NGC 1055. NGC 660. NGC 266.
IC 2003. Piccola planetary Perseus. With pushing the magnification differed from the stars. However, the poor seeing did not allow to have the stars, and then point the effect was somewhat reduced.
IC 348. It seemed almost a halo due to secondary tarnished! Except that there was only around that star.
M76. I wanted to compare the vision with that of August. The outer halo of the nebula was still visible, but much less evident, even at 360X magnification of the pushing. We also compared the Pentax XO 5 mm Pentax XL with the 5 and 5 mm with Burgess. the XO actually showed a bit 'better to limit some starlet. But has the effect of the keyhole and the eye relief does not exist.

Val Visdende (10/16/2009) Southern


Finally, on Friday, we also explored the Val Visdende (the picture is the starting point in Mestre!). This probably closes the circle of possible sites for observation on the North East as the crow flies is only a few miles from the Piave sources. The Peralba seen eastward E 'at about 1300 meters above sea level, well protected by a ring of mountains is not very high along the northern arc. To the south is a free fork pointing right at azimuth 0 ° and allows you to see objects in meridian up to about 10 degrees above the horizon (up to about -35 ° declination).
The mountains protect it from wind and the temperature is milder. There was a few degrees below zero and the still air does not hurt (at the time the Three Peaks, there would be 12-15 degrees below zero, winds to 22 mph with gusts to 44 mph - according to weather data). The downside is the seeing that in the valley is not good if it is above the ridges surrounding the wind blows. In fact seeing the beginning did not allow to use more than 130x (otherwise not have star point). Over the course of the evening is a bit 'better. Sure, you can have pinpoint stars at 260X in the deep sky images is an advantage, but this only occurs regularly in the Three Peaks. The extraction fan boundary layer nevertheless worked well and there were no signs of the boundary layer to add damage to the image.
The access road is easier and seems to be open all year. So this is a good alternative to winter Casera Razzo. A little 'more distant from the plain, a little' less cold, a bit 'lower (resulting in higher extinction) and the South freer horizon.
There are hotels in Santo Stefano is open all year round. We were at Krissin: € 48 including dinner and breakfast (ask for Lara, there is no problem to return at night). In fact when we arrived at the hotel the sky was overcast, so we take the room without supper. When we arrived in Val
Visdende were no clouds in flashes but then, before midnight (as forecast meteo.it) was open. We placed in the widest part of the valley, just north of the church. Some houses were inhabited, but the lights were all gone, except for a lighthouse at the entrance of the valley (but it was a couple of miles before where we were and thus invisible). I'll have to report it because it violates the regional law against light pollution (plus you do not understand what it is used).
Although it was open, the sky was not perfectly clear, or perhaps it was only 1300 m above the extinction is higher than in 2300. The Milky Way was not opposed to the Tre Cime. The sack of coal of the North was always the blacker the sky, but it stood out in the same way. The SQM showed average values \u200b\u200baround a 21.49 (dopo mezzanotte) fino a circa 21.45 verso le due e mezza di notte. Rispetto al 21.55-21.60 delle Tre Cime, e complice anche la maggiore estinzione, la differenza si vedeva... starei per dire che c'era un "abisso". Anche al telescopio. Ho voluto controllare NGC6946, senza poter usare gli stessi ingrandimenti delle Tre Cime (questa volta circa 170-200x, mentre alle Tre Cime anche 260x). Questa la descrizione del 27 agosto : " Potevo vedere le spirali, e potevo anche intuire diversi nodi di stelle lungo le spirali. Non credo di averla mai vista così bene. Il nucleo era cosa a sé: più luminoso e fine. Infine si poteva percepire l'intero alone debole della galassia ". Questa volta invece dell'alone esterno there was no sign and there were only two good arms. Nodes even the shadow of stars ... Definitely, Maybe if I had a special refractor I would see even better live Three Peaks ... but I was only a Dobsonian 400, with extraction of the boundary layer and optical lambda/8-9 by Zen (interferometric test). Mv
The limit was about 6.5-6.6 (the Three Peaks 6.8-6.9). M33 was visible easily distracted, at times almost in direct and had a clear appearance nebulare.Era but very high in the sky.

Light pollution filters from throughout the South By South West may come from Santo Stefano di Cadore. The clouds above the valley were black, with the exception of those that leaned toward Santo Stefano, illuminate dal basso. In ogni caso, sparite le velature, l'orizzonte Sud non era poi molto più luminoso di quello Nord (ad una osservazione non attenta poteva passare inosservato, non a me e a Mar4ever il namibiano ).
Anche dalla forcella Sud filtrava luce. Eppure a Sud c'è solo il monte Terza Grande, più in là c'è Casera Razzo e poi altre montagne fino alla pianura, fra i 60 e 110 km di distanza. Probabilmente stavamo osservando la luce della pianura, un po' come dalle Tre Cime .
Lungo l'orizzonte Nord c'era un po' di luce, che a giudicare dal colore uscito nelle fotografie (verde) era probabilmente l'airglow.
Marco ha scorto per primo il Gegenshein nei Fish. The high position in the sky and the distance from the Milky Way (this is the best time, as well as when it is in Cancer) has allowed to see him from a sky of 21:45!
When disassembled, the telescope was covered by a thick layer of frost. It 'was then that we realized that the refractor would be even higher really deep sky , except that maybe some jewels are not taken willingly to take the ice.

Some items observed.
NGC 246 in Cetus. A beautiful planetary nebula showing different light and dark some stars in it. I dare not think how it could appear in that 155 mm showing the central of M57.
NGC 210 in Cetus . It was noticeable at the core, the bar and spirals. Picture a little 'affected by light pollution in the South appeared smaller than the picture in the link, but the star was visible on the spiral (also served here might be another refractor, you know ... "is not sensitive to' light pollution ").
NGC 7380 in Cepheus.
NGC 7822 in Cepheus .
NGC 1360, in Furnace . It 's a very large planetary nebula is interesting because, with the OIII filter shows three darker spots inside (a little' as the Owl).

Namibia 20/26 April 2009 Part Four

( Episode 1: general description )
( Episode 2: star clusters )
( Episode 3: nebulae )

finally conclude the report of the observations of the southern sky . In this latest installment we talk about galaxies, including of course the legendary Magellanic Clouds.
Obviously not list one by one all the individual galaxies, because they are really a lot, but describe the most important and major groupings or clusters.
Start with the part of the sky to the north of the Milky Way, where lies the constellation Hydra. Finally I was able to see NGC 3109, which I had missed previously because Casera Razzo always fell behind the mountain five minutes before I tried to point it! This is a large elongated irregular galaxy about 17 ', and is the device of our local group. Heading east is the beautiful spiral NGC 3621, consisting of a large nucleus and bright as M81 but more irregular arms and outer glow very weak.
Then there are two beautiful cutting galaxies, NGC 3717 and 3936, the elliptical NGC 3885, 3923, 3904, and finally the queen of this constellation: the Southern Pinwheel, aka M83. It 's very difficult to describe what you see if it is high in the sky, we have admired for good by comparison with both Dobson. As early as 25 cm were very easy and the spirals showing various details, then in 50 ... Always
hydro, there is also a good group led by NGC 5078 but I have not looked on this occasion. Instead I moved briefly to the north to see my best Sombrero (M104) of all time and also the famous Antennae in Corvus (NGC 4038/4039). Of the latter had not seen the very small arms but the nuclei had few details.
brings us to the Antlia, constellation anonymous and difficult to detect, but inside it contains a myriad of untold galaxies! The largest is NGC 2997, a magnificent spiral seen almost face-with arms very bright and has little to envy to the most famous turning of the first. The declination is more or less the same as that for M83, with a little 'hard work, can also be seen from Italy. Then there is a spectacular
storage, slightly lower (-35 °) but still affordable by our south. If I'm not mistaken is the third largest in the sky after Virgo and Fornax, and its main components are NGC 3258/3268/3271/3281 etc.. It is to literally get lost in and I with two feet and a field of 50 'I saw a dozen galaxies at a time, an unforgettable scene!
Then there are other nice little groups like NGC 3095/3100/3108, NGC 3113/3137/3175, NGC 3223/3224, NGC 3347/3354/3358. In all in this constellation I scored as many as 36 galaxies!
And then comes the Centaur. Needless to say, NGC 5128, also known as Centaurus A, was one of the main target of this expedition, as a galaxy is unique and there is not any that even remotely resembles. In other words, completely revolutionizes the concept of "black band"! This feature that bisects the ball of light is already clearly visible at low magnification in 80 mm, and then in the large openings are completely detached from the background and a slight fork in 'Y', with a star just above the point of separation ! It turned out instead
a bit 'disappointing NGC 4945, because despite being a giant slug of 18', is very weak and virtually no details. I expected a great copy of M98, with lots of light and shade, and yet it is little more than a diaphanous spot. You can not say it's ugly, but given the photographs and the excellent observing conditions in which I would find myself, I expected more. Nearby there are also elliptical NGC 4945A and NGC 4976. Stumble
NGC 5102, we might call the "Phantom of centaurs iota" of the proximity to the star in question, making it similar to NGC 404 in Andromeda (and is also the case for elliptical!).
Then I looked some more and in galassietta Cen A and omega center, while I have not had time to look at other in the north-west to the border with the Hydra.
conclude this first part with three spiral galaxies in the Wolf: NGC 5530, IC 5643 and 4402, respectively 3 / 4, to face and cutting.

Now climb over the galactic plane and we move in the constellation Fornax, the fate similar to that of Antlia: asterism as insignificant, but phenomenal in terms of the objects within it. Although in April it saw very low in the early evening, I was able also to give you some quick look before it went down. The ammmasso is located on the border with dell'Eridano mouth, and galaxies are more elliptical NGC 1316 (Fornax A), NGC 1374/1380/1387/1399/1404 and barred spiral NGC 1365.
All I have seen 19, but there are many more because I skipped all those in the northern constellation (from 1097 up to speak) because at that time were not much higher as seen by us, and then try with more time to observe Italy soon. Even in the southern part
dell'Eridano there is something cute, like NGC 1532, but a sort of sombrero with an arm that extends to the outside and the small companion NGC 1531 perpendicular to its core. Perhaps this couple is similar to M51 except that it is seen almost instead of cutting his face. Then there is NGC 1269, a disc galaxy similar to M94, with bright nucleus and then the outer glow is difficult to see due to glare.
go to clock, we find the deformed galaxy NGC 1249, the barred spiral 1433, then 1448 to cut the face of 1493, and the pair 1510/1512. In short there is something for everyone!
in Colombia, not far from the globular cluster NGC 1851, there's quite a trio of galaxies aligned within a degree and a half: NGC 1792/1808/1827.
Then there is the golden fish that, as if not more, than the cloud also contains many fine galaxies more "normal". Moving from north to south are: NGC 1515 with the cutting side of the sixteenth 1515A, NGC 1566, spiral semibarrata, a group of elliptical in its surroundings (NGC 1549/1553/1617), and the two spirals of NGC 1672 and 1703 face. In
Lattice stands the beautiful irregular galaxy NGC 1313, 8 'in size. It 's very bright and full of detail, with well-perceived HII regions. Can be defined as a cloud of Magellan in miniature, and coincidentally is also about half way between them!
from another galaxy NGC 2442 is in spectacular shape voltante Fish. No need to say why, just look at the photos.
For those who still want to try their hand stuck to bright stars in galaxies, in Hull is the Phantom of Miaplacidus, NGC 1822. And, even if on purpose, this is elliptical!
On the main there are three major discrete spirals, NGC 6215/6221/6300, while the nearby Peacock we find one of the largest (20 ') in the southern hemisphere, namely NGC 6744. But the second half proved to be disappointing after the cutoff of the Centaur, because I would have expected a beast as M81 or M101, whereas its spirals are much more fleeting and difficult to discern, even with half a meter. So I found it more like a cross between NGC 6946 and IC342, although the nucleus brighter than these two. Is also an object to look absolutely if you make a shipment over the equator, because there is the interesting detail of the outer arm to the north which crosses the galaxy NGC 6744A with the perspective of magnitude 15, a real challenge!
The Indian medium and small swarms of galaxies, it is pointless to list them all but I must mention the beautiful cut of NGC 7090 long 7 '.
Even in the beautiful constellation of the Crane is to be lost, but given the unfavorable season for your comments, I just look at the most important group, which consists of NGC 7496/7552/7582/7590/7599/7632 In addition to planetary nebula described in the previous episode.
Same goes for the sculptor, that could be seen down just before dawn. The main galaxy (NGC 253) was virtually cut off and I would not view some of the best from Italy, so I focused on other major companion galaxies in its group, located in southern declinations, and then, for Fortunately, more visible in that circumstance.
Large spirals NGC 300 and 7793 are obviously very good but the meanness did not do them full justice, while the 55 was a scream! It 's a huge sigarone 125X half a degree that filled the whole field, with swelling evident irregular on the west, while the two extremities faded and seemed to never end! E ' was undoubtedly the most beautiful of the novel set in Centaurus A. In Phoenix
instead there is virtually nothing, apart from little things reserved for fans of the various small groups as Stephan, Copeland, et cetera. For here we find the quartet of Robert, whose components are of magnitudes from 13.8 to 15.0, and catalog numbers are NGC 87/88/89/92. Even the nearby PGC 1452 is easier than 3 out of 4 members of the group! (But then why was not included in a catalog more "noble" as NGC or IC?).
Tour is almost finished, now come the main dishes ...


Magellanic Clouds

Before the trip I had poked around in a forum di astrofili australiani per leggere i loro commenti sulle due principali galassie satellite della via Lattea, e sono unanimi nel considerarle gli oggetti più spettacolari e ricchi di tutto il cielo, aggiungendo che noi poveracci dell’emisfero nord non abbiamo la minima idea di cosa siano finché non le vediamo! E infatti ho potuto verificare che hanno pienamente ragione. Mi è venuto il dubbio che la mia impressione tendesse a sopravvalutarle un po’ per via dell’ovvio effetto novità, ma sembra che gli australiani non si stanchino mai di vederle sempre, e addirittura c’è chi ha rinunciato alla possibilità di andare a vivere negli USA proprio perché non voleva perdere le sue amichette!
E anche io ormai consider incomplete sky with a low shot galactic core and without the Magellanic Clouds, and I can not think back to all those daily hours spent in perdermici.
Another consideration is that they are good for any aperture and any enlargement, because every circumstance highlights a number of details:-
to the naked eye are perceived main forms: the small is shaped like a pear, with the most "chubby "SW, while the largest is almost round, with the center the great light bar elongated in the direction EW (a bit 'like the capital Greek letter Theta). The Tarantula Nebula (NGC 2070), to the east is visible in averted.
Just to give you an idea of dimensioni, per coprire interamente la Grande Nube ci vuole (a braccio teso) un pugno chiuso!
-col binocolo o con un telescopio a bassi ingrandimenti si intuiscono le strutture principali quali i pseudo-bracci, gli oggetti più grandi, le diverse densità stellari, e tutto l’aspetto è brizzolato, cioè si capisce che è un grande insieme di stelle anche se non si risolvono nitidamente.
-coi Dobson si possono approfondire singolarmente tutte le decine di oggetti contenuti, tra nebulose, ammassi aperti e globulari. Essendo galassie giovani e irregolari, sono estremamente ricche di regioni HII, e trovandosi in posizione di faccia (in particolare la grande) non ne è pregiudicata la visione, a differenza della Via Lattea that prevents us from seeing the objects in more than half of its volume because it is cutting.
In these clouds is sufficient to move the event far and wide to see in each field at least one or more objects, and with a decidedly Dobson is an easy and fun. If you want to identify clearly what you see, then you need to get steady work with a map and a detailed object-hopping!
think that in two nights I've been watching the cloud for more than three consecutive hours, I was totally caught as a drug! After a while, 'I began to say: "enough is enough, I have to watch something else," but then continue to go over that immense maze back and forth, and eventually I stopped only when it became too low horizon. Fortunately that should not go in the southern hemisphere in the summer once or else you would risk going there in December to observe only there for a whole night!

The cloud was rising rather less at night, and being smaller is not this speech, and then there's the globular to attract attention!
To understand that I am not exaggerating at all enough to see a detailed map as Google Sky or this beautiful mosaic labels.
And thanks to these pictures do not need to list all individual items, but I just describe the main ones. Most
parte sono catalogati come NGC e IC, anche se ce ne sono alcuni di rilevanti che però sono inseriti solo nei cataloghi specifici per le nubi, come ad esempio il globulare Kron 3, situato prospetticamente vicino a 47 tucanae.
Si nota subito che la Piccola Nube, in proporzione, è più fornita di ammassi globulari, e in assoluto devono essere anche molto grandi vista la distanza. I più grossi sono NGC 330/339/361/416/419. Non illudetevi di risolverli facilmente, sono una sfida ardua esattamente come i globulari del Delfino e della Lince...
Le nebulose maggiori sono NGC 346/371/395, situate nella zona NE. Facili, luminose, contrastate e dettagliate. I filtri UHC od OIII comunque sono sempre utili. A SW invece troviamo NGC 261 e 267, and finally in the SW suburbs, leaving the dense part of the cloud, NGC 456 and stand 602.

Turning to the older sister, the eye automatically falls first on the Tarantula, in one of the most haunting of all the heavens, if not the best. Here, as the Centaur and the hull, we pulled the screaming at first glance be censorship.
We're talking about a cloud of 20-30 'with a surface brightness comparable to that of M42 and a lot of details and dizzying contrasts, and to make matters worse is surrounded by equal volume of various objects, and so if we consider the whole complex to NGC 2084, obtained a field of about 1 ° which is a total uproar! The nebulae that surround the main are NGC 2048/2060/2069/2074/2077/2084, 163/164 Henize, then we have the globular clusters NGC 2100/2108 and NGC 20372042/2044/2050/2055/2081/2093 open. To get an idea of \u200b\u200bwhat you see us just take a picture as the one linked before and put it in black and white! And those clusters of stars that appear blue in the picture, in view of 50 cm with well resolved, thus creating an effect of carpet of stars that are intertwined with the nebulae. In short, there is nothing in the north that might resemble this amazing show!
in that area and also the supernova 1987A exploded, I think I have seen the balance because I had taken note della posizione esatta (si trova presso NGC 2044) e mi sembra di aver notato una stellina leggermente sfocata, ma per essere sicuro che fosse proprio lei dovrò informarmi meglio. In rete non sono riuscito a trovare nulla circa la possibilità o meno di osservare visualmente questo oggetto.
Anche la zona settentrionale della galassia (la porzione staccata dalla barra principale, per intenderci) è altamente spettacolare, perché ci sono grumi e trame di stelle mescolati a chiazze di nebulose sparse. Perciò questa regione che comprende NGC 1934/1948/1955/2014/2027/2030/2032/2095 eccetera, seppur meno concentrata del complesso della Tarantola, ha poco da invidiare e merita anch’essa di essere gustata per bene.
Altri objects and groups of particular interest: NGC 1727 and its surroundings, the globular cluster NGC 1763 and 1783, NGC 1770, the trio NGC 1850/1854/1858, respectively open cluster, globular nebula (find another case where we can see an object type in the same field if you can!), NGC 1876, the nebula in the shape of 'S' NGC 1910 (right to highlight this feature we need a filter, otherwise the stars surpass it), NGC 1918, the group of 1934, that of 1965, and finally the nebula NGC 2018, 2075, 2103 and 2122.


CONCLUSIONS

I hope I have provided a good guide for those who want to try a similar experience. I think that for those who are passionate deep-sky it is not just a whim but a genuine point of arrival to do at all.
All these comments I wrote them after the trip based only on memory, because during the observations by writing only the catalog numbers of objects observed, but no special notes. So do not rule out the possibility that there are errors in evaluating the degree of difficulty of the visions, and it would be interesting to compare these impressions with those of other people ... or with myself when I come back! Because it is obvious that there is a great desire to return, all 5 have just said "goodbye." I'll certainly not next year but We hope for 2011, perhaps in a different season (August or September) so you can see the constellations of the zenith at the galactic south pole that are low in April.

Last night I watched it again Jupiter. The seeing was not the best. For most of the night was enough to move the focus slightly extrafocale to see the current high-altitude turbulence. Jupiter appeared as seen through the exhaust trail of an aircraft. Focusing on the current Jupiter was no longer visible but the image was not sharp. Even in these conditions, the aperture of 10 cm did not produce any improvement. In fact you could see the details that were still less.
Later when Jupiter was high, there has been a better time that lasted about three quarters of an hour. During this time I could zoom in a bit 'more (instead of 170x 260X) and the image remained sharp enough. I found this picture online, which is a little later at the time of my observations. Overall, the picture makes it quite a good idea of \u200b\u200bwhat was visible. In fact the image was recorded at the telescope, but it was necessary to fix attention on a small area at a time. Some details visible in the photos were vanishing from the truth (in practice only in the equatorial zone is sensed there was something green, but had not seen the festoons of the photo). On the contrary other details were more marked from the truth. For example, the small dark area below the oval was much more evident.
I scored some of the details that were visible: more than a second oval oval uncertain (seen once), the STZ before the pole, while the NEB there were several areas with sloping trend (I have marked a) and zones a lighter color. Besides there were some areas that could have been clearer look of the oval. Here the photo does not make the contrast of reality. Several divisions and other details (for esempiop northern hemisphere) were visible but I have not scored more.

How Does Normal Period Blood Look Like

Continuing to explore ....


Yesterday I went for the fourth time the Three Peaks. The weather forecast said that it would be open to the 23, but that there were more clouds and thunderstorms to the south And it did. The panoramic photo (click to enlarge) is made at 23.09, when the sky was opening up. As expected in the South were thunderstorms and clouds that were visible along the horizon line. Also this time so I could not see the true pontenzialiutà of this site, but I've had a taste, with the beautiful Milky Way down on the horizon the clouds. Kaus Australis, the star at the bottom of the "teapot" when the photo is 5 ° in height (azimuth 206 °). I estimate that the horizon in that direction is about 2 ° high.
peaks at about 7 ° South are high. E 'visible Sgr theta-1, which at the time of the photo is 8 ° high. (Azimuth 184 °). Towards the eastern horizon
down again. Except for some peak on the horizon is an average of 2 ° -3 ° high.
On this occasion, you see clouds up to about 6-7 ° high. I think they are clouds over the plains or at least halfway, and illuminated from beneath the plains. Misurina is visible in the lower right, accompanied by a halo of light that is the hotel that I have photographed lighthouse in the previous article. I expect the sky disappearing clouds and moisture to become much better until the horizon line. When the fog disappeared Misurina disappeared on the lights of the lighthouse (though I think it's one of the cases to apply once the new regional law The ILO).
course, if the horizon was covered by mountains south there would be no view of distant clouds. But it would be just a way to ignore the problem. The plain to the south is 140 km. A South East 90. TITUS Overall, the picture does not seem dissimilar from those of average Americans p arches, where 200 km produce flashes of light along the horizon as these.

When the sky finally opened at all, the Milky Way at the zenith was well defined, the lot of North blackest coal, and the SQM measured between 21:55 and 21.60 (the Milky Way). I do not think can score more, because that is the light of the Milky Way. I estimate a visual magnitude limite di circa 6.8, usando le stesse stelle di riferimento che ho detto in precedenza.
Verso il mattino si è vista la Luce zodiacale molto bene. Sembrava quasi inquinamento luminoso, ed era molto più luminosa della stessa Via Lattea. Inutile dire che non era colorata di giallo né era percepibile la presunta differenza di colore con la Via Lattea (bianca), come invece direbbe Bortle (non sono il primo a osservare che su questo punto della colorazione la scala di Bortle ha qualche imprecisione). La Via Lattea invernale appariva come una fascia chiara nel cielo. Sotto c'era una fascia sensibilmente più scura, circa in corrispondenza di Andromeda. Sotto ancora, in Toro, Ariete, Persci c'era di nuovo del chiaro. Dalla parte simmetrica del cielo, West, more distance from the Milky Way in the sky was dark as Andromeda and even more bright and nonc'er no band corresponding to the Taurus-Pisces. The horizon was polluted South
as mentioned, but it must be said that the picture was taken with prolonged exhibitions Exhibitions (30 ", ISO 1600, F3, 5) and does not reflect the real live feeling. In fact, looking at the South could not be discern the clouds like in the picture, but only a slight flare. Least stood out the color of the clouds. The clouds at the top, like the one that covers Jupiter, appeared dark (though the photo shows that are dimly lit). You could see only the halo around Jupiter.

One great thing about this site is seeing. After the experience of the two previous times I have been monitoring the weather seeing of meteoblue and I could see that, on average, about twice the seeing is better than plain. It seems to me that the thing can be justified if one considers that the observing site is over the worst layers of the atmosphere (not in a basin as Casera Razzo). The fact is that last night the seeing was excellent.

We observed Jupiter. You could also use higher magnifications, but I wanted to observe 260X, to enjoy an image with a wild fineness of detail and engraving that I have rarely had at home. To understand, I could see the rise of the Red Spot. He saw "half" al'orizzonte! Not only that the stain had its color, SEB another well-defined color, and the area that separates the SEB from the spot (well resolved) yet another color. The NEB can be resolved in detail each of which had a shade of their own and different from others. Of course we have not been there for so guardareb Jupiter, because we went to do deep sky, but there is no doubt that this is also a site to make high resolution.
Since I'm on the subject of planets, I mention the observation of Uranus, which we have seen three satellites, and Neptune (a satellite). Before leaving we also saw a 6-Mars, "which showed the stage, caps and some detail on the surface (but it was choppy on board one of the Three Peaks).

To go to the Deep Sky objects: I left with a rather long list, with different exotic objects, but then the "negotiations" with Marco (who had his list) have led to a compromise.

An object that I want to mention now, although we have observed in mid-night, is NGC 6946. I did it on purpose to observe once again check the level of detail visible. I could see the spirals, and I could also imagine different nodes of stars along the spiral. Do not think I've ever seen so well. The core of what was to him: more light and fine. Finally, you could feel the faint glow of the entire galaxy. We watched a bit the 'at all magnifications but the best came out to 170x with the Pentax 10.5 and 260X with the 7 Nagler. The fact that the galaxy was in the darker part of the sky, and seing played in favor. In particular, the seeing allowed to use magnification while maintaining high image contrast. The stars (those sufficiently weak) were in focus in the center of the field by a dot and a flash. Too bad the board is also correct in Newton. I wanted a Paracorr! A

secono object on which the seeing was crucial was the planetary nebula NGC 6886. The nebula has a diameter of a few seconds of arc and is reported to be stellar in appearance, but at 260X, focusing on, the stars formed the head of a pin, while she remained increasingly blurred. A fire could feel the pinpoint stars and the nebula as a fuzzy ball.

Abell 43. A nebuolsa planeatria that we could see the 130x (better filter). To me it seemed to receive a reinforcement ring. IC1295
also observed, with the globular near 6712. I'm not sure that he saw the small planet in the midst of two (PN G25.3-4.6), which incidentally does not even see in this picture .
Look also at the global 6818, and the dark nebula Barnard 150 (near NGC6946), which saw the largest nodule at 86x, but I did not follow (we did not change quickly for the eye), the stringy part.
Unsuccessful attempt identify BSI 149, Sh2-136, BSI 152, but perhaps more for lack of organization and quickly (they were not in the list that Mark wanted to go beyond!).
NGC 7023, osservatra like a light with some wrinkling around the central star. Note also the two
Gaassie NGC 7332-7339, which is perhaps a bit 'weaker than in this photo .
Finally on my list have saved some Abell. The 45, 61, 71 and 72 ... but now I can not remember what they were visible and what not! The next time I write, I should also observe only 20 items instead of doing the marathon to observe 70.

List Of Marco, we did:
NGC 6384, which I have a percept elongation and "something" of spiraling. In fact it seemed to me a bar with a ring. NGC6572 (no comment). Barnard's Galaxy (vaguely visible at 86x, at 56x almost gone (unfortunately we have observed several items in the unfavorable sky.) NGC6907, 7184 (no comment). NGC 6886, which I mentioned above.
We observed in the Vulpecula open clusters and nebulae 6820, 6830 and 6823. was faintly discernible through the haze before the eye as he watched a UHC filter with the 32 mm eyepiece (56x). Also in the Vulpecula 6813.
Finally, NGC 6842 (no comment).

this observing session, more than others, but I convinced that you should limit the number of items in the list, and, above all, should observe good and slowly, just taking notes and maybe even doing the drawings. Otherwise it remains just a list of what we have seen but can not remember how you have seen.

Even the Three Peaks. 19/08/2009


Cassiopeia and Perseus rises behind one of the Three Peaks, to 00,54, 23 August 2009. The mountain in the foreground is lit by debolemte car that was coming, would otherwise have been as black as the background.
for the third time I came here to better understand the quality of this observing site. Even this time the conditions were ideal: in the afternoon a storm front had passed e, sebbene le Tre Cime fossero ormai sotto il cielo sereno, verso Sud si potevano vedere ancora le nuvole e il temporale allontanarsi. Le nuvole sono state visibili per tutta la notte anche quando erano sopra la pianura e le condizioni non sono state mai perfette. Tuttavia questa volta ho potuto capire molte cose.
La prima è che Misurina e Auronzo hanno un effetto limitatissimo sul sito osservativo, se le condizioni climatiche locali sono buone. Le due volte precedenti le luci diffuse di Misurina erano dovute a nebbiolina e umidità che si estendevano fino alla altezza del luogo di osservazione. Questa volta la situazione meteo locale era buona: non c'era umidità, vento a tratti sostenuto e temperatura di 5°C. Misurina e Auronzo erano finalmente ridimensionate a few lights in the darkness of their valleys and did not produce halos that extends above the skyline.
Instead, further, the situation was quite different. From up here the view stretches far away, and in some directions, the horizon is negative (especially to Friuli where the line of sight passes over the sky of roughly Casera Razzo and over mountains about 2200 meters, which are less high share of observation). The clouds above the plain fiulana (100 km away!), Which were in sight, appears to be illuminated from below. If the horizon was hidden would not have seen, but the light coming from there would still potutto illuminate the sky of the observation point above us (it's what happens Casera Razzo and partly to Peralba, where the horizon is not visible, but there comes the light that illuminates the sky).
From here you could see the least guilty. I made panoramic pictures made at different times of the night. As the clouds moved away situazine the best but it was always a degree of brightness of the atmosphere above the plain. I easily detected Udine, Veneto plain, Cortina, Trentino and Alto Adige.
The amount of light coming from the plains (100 km from Udine to 150-200 km in the rest of the plain) is not much. The zenith, and this is good news, it was 21.60 on the Swan! And this in a situation where the skies of the plain shone probably more than normal. I'm pretty sure that above Casera Razzo fly at the same time much more light than usual and that the sky was so below average. Here, even in below average sky is saved. But unfortunately it is not perfect: the greatest flaw is that the whole southern horizon is not perfectly dark. Do not you badly, but you can not see the airglow in the South and the contrast is lowered. I'm talking about a band of about ten degrees above the horizon. More on the situation quickly becomes good.
Constellation Capricorn seemed like the "high". I saw the Southern Fish, the teapot that sank in the mountains. There was a bit 'towards the horizon of extinction. I think it was the other side of the coin delle cattive condizioni meteo a Sud. Alle 2.37 la stella Iota Piscis Austrinis (Mv 4.34) era visibile ad una altezza di 8°, e non era certo il limite. Theta, mv 5.01, era altrettanto evidente, alla altezza di 10°. Se assumo grossolanamente che l'intensità di queste stelle fosse simile alle stelle di mv 6 allo zenith, posso stimare l'estinzione in circa 1-1.5 magnitudini a 8-10°. Poichè a questa altezza la linea di vista attraversa circa 5-7 volte lo spessore di atmosfera allo zenit, ne consegue una stima indicativa di estinzione zenitale pari a 0.17-0.25 magnitudini, che potrebbe essere vero per un sito a 2400 metri. Ma non è detto che la trasparenza in direzione Sud fosse la stessa che allo zenit.
Allo zenit ho stimato la mv limite in 6.8 (stars in Pegasus 6.80 and 6.73 in Hercules, which I mentioned in previous reports were visible in averted with a degree of continuity). The only thing a bit 'out of tune was the visibility of M33 with the naked eye, which did not seem sublime.

This time we chose the square for the comments higher. Thomas and I were with my 40 cm: Mirko has not achieved because the telescope ready to load into the car broke a screw in the support of the secondary.
The choice of the site can also see the high rise of costllazioni east (we could see the zodiacal light). Unfortunately it seems that this square is also preferred by lovers of mountain climbing, that did not allla get nothing but dribs and drabs during the first part of the night. The typical behavior was to arrive in the square, stay a while 'time to decide on which parking space (there were so many who obviously was difficiel choose). Someone did several manual conveyor changing place, of course, with its headlights on. Then followed the preparation stage dellla equipment and finally the lights went out ... just in time for the next arrival. I think for them both imprtante in the front row (someone had even put the boots in a row under the machine ready for use) to be ready to "shoot" the rising of the sun (the guess is that there is a kind of " unreported race who comes first "). Some had even placed at the base of the rock, above the scree and slept in the wall. "Slept" I think esgerato often as every turn on the lights and I have not slept well.
We tried to make little noise. But I guess they thought we were crazy to watch the sky. One thing is certain: there are more passionate amateur climbers. Or rather, amateurs who come to observe the sky in places like that. Amateurs who "can not move" and looking to the skies as dark and as preposterous is seeing any. I do not know however that we are Apassionata the mountain "can not move" and that are climbing the stairwell. Let

List of the observed objects. I mention those on my list. Thomas has even more pointed, especially while doing the views.
NGC6946 was one of the best views ever of this item. The spirals were visible: marcatissime not like those of M51 but still visible and not merely theoretical. To me it seemed even to see some lumps of light in spirals. The outer halo of the galaxy was, and you could see the sky, beyond a certain distance became darker (as if there was a dark cloud around). The nucleus was clear and detached from the rest of the galaxy. Another pop 'of darkness and transparency and diameter Equest object should be spectacular.
We then moved on IC1369 and the nearby nebulosa oscura LDN 970 (Barnard 361); NGC7048 era un dischetto ben visibile; NGC7008; NGC6818; La Helix (secondo Tommaso una delle visioni migliori di sempre, io non ne sono sicuro). Ho osservato Barnard 143 e 142 nel binocolo 15x70.
Siamo poi andati sulla Bubble Nebula, osservandola a diversi ingrandimenti. Era possibile vedere bene, intorno a 170x, la parte più intensa del'arco e la parte più intensa della nebulosità come in questa foto .
Del quintetto di Stephan abbiamo visto forse anche la sesta. La mv limite al telescopio era 16.1 (forse 16.6) a 360x. La IC1296, vicino a M57 era intuibile a ingrandimenti intorno a 260x.
Abbiamo osservato una manciata di Arp e la Jones 1, che a dire il vero a me seemed less than engraved Sivell. We observed M27-magnification supported and I'm to see details inside the stem and ears. M76, however, beyond the usual stem, showed a very faint outer halo 360X.
All in all, most of the objects was more visible than usual, with several exceptions. I definitely missed several things.
The seeing was good, although not paragonabiole than last Thursday. The definition, thanks to the extraction system of the boundary layer was also good on deep sky objects, and perhaps this helped to grasp the details of such irregularities in the spiral NGC6946 or M27 in detail.

Plasma Donation Idaho

observations of Jupiter on the evening of August 19. It was to test the new system of extraction of the boundary layer, which will make a separate article. The system works by sucking air from the case of the mirror. In front of the mirror is a diaphragm opening of the mirror itself, so that the only entrance to the air is an annulus formed along the edge of the mirror and diaphragm. In this way the air is sucked from the whole circumference of the mirror, and "pulling" the boundary layer. This was the first serious test and it went better than expected. The boundary layer is continuously removed and the image is similar to what you have in the first minutes after an energetic cooling front. But here the process is continuous, there is now and the quality still remains (as the cooling front should be repeated periodically).

so I could concentrate on the planet. At 245x the image was immediately sharp. I have not had to do the usual "scale." He could also accept higher magnifications, but I found that the number of details that I could see was higher than I could draw. So I decided to limit the magnification to 245x, in an attempt to facilitate the work of design (these are my third and fourth drawing of Jupiter). I had many difficulties both in locating the correct details that drew (after I realized that I had drawn that I had not messi nel posto giusto o alla scala giusta). I disegni sono quindi un po' distorti. L'altra difficoltà è che non riuscivo a disegnare tutti i dettagli. Dopo che avevo disegnato un particolare, riguardandolo mi accorgevo che non sarebbe stato proprio fatto così.

Comunque sia questo è il risultato. Il Primo disegno è stato fatto alle 20.45 TU. La zona polare Sud (in alto) mostrava chiaramente la divisione con la SSTeZ (per la nomenclatura mi riferisco a questo http://stars5.netfirms.com/jupnom.jpg ). Nella SSTeZ c'erano delle aree più scure e in particolare un ovalino bianco seguito da un'area più scura. Devo anche dire che il giorno seguente, alle Tre Cime , ho potuto vedere Giove ancora meglio, polar area and the same was resolved in finer dettgli and dashes. The STeZ was visible, especially with some "reinforcements". SEB are generally divided into three. The Three Peaks was resolved in a dense texture and indescribable indisegnabile (for me).
I then set the focus on the NEB (skipping the equatorial zone) because it showed interesting undulations. A first interesting point is left of the drawing, where the NEB narrowed almost to a point. From there started a thin banner on the one hand and waving the other side The first of these seemed to stretch with a puff or to touch the NTeB. Three Peaks to the haunting after this area was incredible: the structure of the NEB can be resolved in a myriad of puffs, riccioli e altro e ognuno aveva una tonalità di colore diversa, dal marrioncino al grigiastro al verdastro! La seconda e la terza ondulazione erano circa della stessa dimensione della prima, mentre la quarta si ampliava. In corrispondenza delle ondualzioni dalla parte opposta c'erano altrettanti pennacchi, ma il secondo e terzo non apparivano sottili come il primo. Avevano piuttosto l'aspetto di zampe di gallina.
Nel secondo disegno ho cercato di ridisegnare il pianeta per vedere se riuscivo a farlo meglio, ma non mi sembra di esserci riuscito. A parte la rotazine, i dettagli sono gli stessi e le differenze sono da attribuire alla mia "precisione" di disegno.

Jupiter Return of the Three Peaks


Yesterday I returned to the Three Peaks, where I had been in September 2008 . That time I found a lot of mist and a bit 'light pollution from Misurina.
Yesterday, initially, the Three Peaks was not planned, but the weather forecast indicated some risk on both Casera Razzo, both Peralba (addiritttura where a storm was expected around 23). Now were going to come out. Faith and Wide, Verona and Trento were parties to do the route via Bolzano, Val Pusteria, Dobbiaco, measuring spoon, Auronzo, and then on to Peralba or Casera Razzo. When I heard that they would move to Misurina I checked the weather forecast for the area, which were the best. So
was that I'm back there. There were several reasons to return: first the horizon, that the Three Peaks is the best: only a few degrees above the geometrical one, as you can see the panoramic photo (taken in early July when I had been there for other reasons). Secondly, the study of light pollution Peralba of Casera Razzo , and Casera Sivell , has convinced me that compared to maps of Cinzano, screens count a lot of mountains, and that three sites are shown above Friuli (first two) or they are too close to population centers (the third). The three peaks are much more secure than the plain. For example, South is the massive Marmarole, 3000 meters high, which does not obstruct the horizon just because the observing site is at 2400 meters high. Cortina is also well screen. Stay True, the "defect" Misurina, in line of sight, and Auronzo (in line of sight but far from the refuge). However, in the first visit to the Three Peaks was a lot of moisture, and so I thought it best condiziuoni in these two "flaws" may be negligible compared, for example, those of the other sites mentioned. In other words, it seemed appropriate to visit the site again to see what was in the best weather conditions.

Unfortunately the weather was not "better." There were clouds and cloudiness, but fortunately we were at the highest level of the clouds and much of the sky was visible. In short, the situation was similar to last time. The veils and clouds over Misurina were lit. During the night I moved on the side of Auronzo and there was a "sea" of veiling below, illuminated from below by Auronzo. Of course, if they were thicker clouds, lights and Auronzo Misurina were hidden, but they were so thin and milky.
We did, however, the consideration that, after all, had gone well, because we were mostly above the clouds and we could observe the sky, even if the appointment was postponed with ideal conditions. There "under" was to be worse, and safe "down there" was both the site of Peralba is the site of Casera Razzo.

Another thing we noticed was that the seeing was good. In a sense we were on the most wicked atmosphere, with clouds and turbulence more below us. Casera Razzo, however, is often in the wake of the upstream Tudaio and rarely seeing is good.
So we have seen (also) Jupiter. It could easily push the magnification and, despite this, the image was full of details. We thus had the opportunity to compare three different telescopes on the planet (it seems crazy to do high-res on a site for deep sky, but in reality, if seeing is too deep there buoon earns e non poco). Per fare la storia breve ne è venuta fuori l'ennesima smentita della leggenda che vuole che i piccoli rifrattori siano più adatti dei grandi riflettori per fare planetario visuale. C'era un NP101, che ha potuto lavorare a 270x! Il mio 40 cm avrebbe potuto usare ingrandimenti maggiori, ma sono stato a 260x. Il 30 cm riflettore di Andrea è stato su ingrandimenti analoghi.
L'immagine era indubitabilmente più ricca di particolari nei due riflettori, nonostante il seeing, che secondo le leggende astrofilo-rifrattoristiche dovrebbe impedire a strumenti oltre 10-15 cm di esprimersi e dovrebbe vedere vincente il piccolo rifrattore. Non è stato così: nel rifrattore c'erano anche meno colori. I dettagli eran meno evidenti e meno contrastati. In qualche caso era ancora possibile, avendo visto qualche cosa nel grande, ritrovarlo con più difficoltà nel 10 cm. C'era un piccolo ovale bianco su cui ci siamo fissati, che era ben visibile nel 40 cm ma invisibile nel 10 cm. Il 30 cm di Andrea, con specchio sottile, era ben acclimatato. Nel mio caso ho usato il sistema di aspirazione dello strato limite che descriverò a breve.
Una cosa che ho notato è che Fede, abituato al rifrattore, guardando l'immagine luminosa nel 40 cm ha detto che era troppo luminosa. Per me il contrario: l'immagine nel 10 cm era troppo scura. Evidentemente ci si deve abituare. Mettendo il diaframma eccentrico di 10 cm sul mio, l'immagine era del tutto simile a quella del rifrattore (confermando fatti teorici ovvi - per chi li conosce).

Ho anche fatto lo star test allo Skywatcher 30 cm. Che dire: nessuna aberrazione sferica, un'ottima correzione del bordo e solo qualche segno di forzatura (un lembo "schiacciatlo") che però non comprometteva il risultato. Sono sicuro che Andrea allenterà i fermi dello specchio... Ah dimenticavo: i "fringe violetti"! Sfuocavao avanti e indietro per stanarli ma niente da fare. E' proprio uno specchio apocromatico!

Ritornando allla valutazione del sito, se l'orizzonte è buono, se la quota è tale che spesso si sta sopra la turbolenza, se spesso si sta pure fuori delle nuvole (e si salva la serata) la cosa che manca è vedere che cosa succede con il meteo giusto. Return.

The quality of the dark was good. The Swan we measured the zenith (the Milky Way) between 21.60 and 21:50 (21:55 on average). Later, with the Swan a bit 'move, the readings ranged from 21.60 to 21.72. It 'possible that this site without humidity and clouds is even better? Probably.
The transparency was not great, because obviously there was some haze. Some clouds coming from the north appeared dark against the sky background (just above the clouds and Misurina Auronzo were cloudy). Light pollution in Cortina seemed a small thing, even in comparison with that for example, St. Stephen's seen Sivell. Since there were no clouds, however, I did the usual panoramic photos.
I saw the star of Hercules in 6.73, while in Pegasus I saw the HD 219310 (mv 6.34) almost directly and, at times, the HD 219487 (mv 6.57) and HD 219418 (mv 6.80). Towards the south the sky darkened and / or fade according to prevail from time to time the clouds of luminescent Misurina or that they were covered by clouds darker. M31 was visible to the naked eye with its structure (you could see the core and the halo). M33 was "awkward." Since it was dark there was probailmente extinction above the norm.

car parks, this season, are used by hikers who sleep the night before the climb. There were several cars with people sleeping. When we arrived a inglese stava montando un piccola tenda. "Montando" si fa per dire, perchè era del tipo che si sviluppa da sola buttandola per terra. Dopo un po' si è avvicinato dicendoci che "non potevamo stare là" perchè lui (essendo in vacanza) doveva dormire per fare la scalata il giorno dopo. Qualcuno di noi (credo Wide) gli ha risposto che noi (essendo in vacanza) dovevamo guardare il cielo per dormire felici il girono dopo. Pretendeva che smontassimo gli strumenti e ce ne andassimo, ma alla fine ha preso la tenda e ha cambiato posto. Più tardi è arrivato un camper: altri scalatori. Hanno manovrato per qualche minuto (evidentemente c'era troppo spazio e non riuscivano a decidere in che punto fermarsi, in più avranno pensato di aiutarci with the headlights to see in all this darkness that was). Throughout the huge open relativcamente have decided to get close to us! They then turned on several lights and went out a long time to turn over the equipment. They finally turned off and put himself to sleep. When it was our time to leave we have repaid the kindness by turning various lights so they do not feel alone in the dark and we drove out evil spirits with the Eastern Rite.
Seriously, living with this kind of "users" of the mountain seems to me problematic. Fortunately, that ended the August issue no longer arises in these terms. Ah ... There were two sleeping bag in the PEL under the stars without a tent on the ground beside the car!

Ho provato gli Ethos! Per la maggior parte del tempo ho usato l'ethos 10, a 183x. Ho avuto qualche problema a mandare a fuoco quelli più corti (il 6 non c'era verso). Ho usato anche il 17 a 107x e quasi un grado di campo. Begli oculari, ma ripensandoci non sono molto adatti a un Newton F4,5 che non ha un bordo corretto (è un po' uno spreco).
Fede ha usato l'NP 101 per la maggior parte del tempo a bassi ingrandimenti (tipo Pan 24 mm a 22.5x, o Ethos 10 a 54x) facendo gandi carrelalte della Via Lattea e degli oggetti immersi nel loro habitat. La correzione al bordo in questo caso paga e ha senso stare su oculari a grande campo. Ricordo la Swan nebula con la sua forma a cigno capovolto nel mezzo della Via Lattea, e il Velo tutto intero, including the triangle of Pickering. We observed several objects
classics. Among these 17 M31 ethos showed dark bands than ever before. M13 was resolved in NP 101, in the sense that, although very weak, Garn of the M13 stars that give the tentacles were visible. Here Faith pushed magnification.
M22 in 40 cm, with Ethos 10. We also saw different densities of stars in the background of the Milky Way globular cluster to the left and right (azimuth). Observed the Seyfert's Sextet, which we saw a couple of galassiette. The planetary NGC6742 of 15 mv in Dragon seemed like a good diskette. I've also seen Neptune as a blue dot and the satellite Oberon. Marco also observed Uranus. An M27 with filters of various type in which it seemed for the first time to see different grades and some structure in both the stem are in the ears (perhaps seeing?). I tried to convince others that the ears appear red and the green seems to stem (the colors are just the opposite but who describes it describes in colorful colr reversed) but there was nothing to do. Andrea said it was all green.

The list is longer but of course these are the things that impressed me most.

Come back we stopped to photograph this shining example of light pollution. From this building just more disturbed that the whole Misurina. With the new regional law must think about light pollution turn off those lights. I think that will signal the situation.

Reflection ....

reading the post on the blog: "us and them", which recounts the dialogue between two mothers Moroccan amazed because a child had been promoted and an Italian child no .....
I dissociate myself from those people as a separate Italian! Perhaps the education of these mothers and their children is not based on values \u200b\u200band truly worthy of being considered "IS"!
advise these parents to go back to school with their children not to study Italian, mathematics, physics, etc. .. But to have children by themselves a bit of culturac he relates the moral sense!
I think they are great to do because of race all children see with eyes of innocence where everything and everyone is equal!!

The right place for this school Shout

For several weeks children in elementary schools received report cards.

I was in a place much frequented by their mothers, the hairdresser, and not wanting to have witnessed a conversation asking what is best for their children ...

Mama y: Did you go to take your child's report card?

Mine has had all 9, but the teacher told me that it is difficult to put 10 so that you can consider this vote as the best.

Mom x: It is also mine. But it is right that put these wishes, children are very intelligent and educated!

In the conduct has 9.

Mama y: yes .. but that also put him in the Moroccan child ...

Mom x: REALLY?!?!

Mama y: And ... and instead have gone to reject the daughter of W.

X Mom: my Mom can not believe it! ...

But since there could not leave the class from that Moroccan! Definitely will make a stink ... above all in the class that hole .... hahaha.

Mamma Y: And just retired ... they do not like us to keep us' edu it.

I have not commented on that day and I will not now ... also because I do not think it is needed.

on one thing though, I thought ... We and the Others, perhaps, yet we must learn to coexist.
