Wandering galaxies over 21.70

The title says almost everything. The darkness was excellent yesterday in Val Visdende, perhaps more than 21.70 (4 SQM readings ranged between 21.66 and 21.76 to 21.60 with some reading but also some more than 21.80. Some small trace of light pollution was visible in the South A middle way between the two situations described in that article (on the plain was very dark).
In the winter Milky Way could capture different degrees of intensity that made her seem a stretch when you consider the very large offshoots. The band Zodiac / Leo was in Gegenshein evident as a light to the rest of the sky above and below, then south to the horizon the glow of light pollution would intervene in the Po to 100 km!). Initially, a few passing clouds probably was dimly lit by the lights of Santo Stefano di Cadore and Sapphire, the two most important towns in the vicinity (of sight). It 's hard to say how much light pollution (21.70 is still two-tenths from perfect) coming from the plains to 100 km and that from these two centers.

The initial temperature was quite mild, around a few degrees below zero and this was maintained for most of the night. But to the early hours of the morning fell quite rapidly to -11 ° C. The road is clear in the part that leads to the valley, with bends and stretches of a certain slope. In the valley and icy roads were partially innervated, but fortunately the roads in the valley are almost flat. The seeing was not great. Towards the middle of the night observing Saturn and blurring in extrafocale was possible to see the effect of cascade sign of turbulent layers at high altitude. But say I do not know if they were high layer or the area of \u200b\u200bwind recirculation that forms when the wind comes off the ridges of mountains (the seeing was good perhaps elsewhere). To make matters worse there was also cold, and the resulting convection currents on the optics. I noticed that the 60 cm, even if it adopts the same system of extraction of the boundary layer of 40 cm, it is slower and more gradual improvement in the quality of the image (I think that can be used perhaps two or three hours to reach the ideal situation).

Lost in a valley with no signs of life (not passed no one and there was a house that seemed inhabited), with the reassuring shape of Peralba to the east and the last larch and spruce that stood out as black silhouettes against the sky northward, the participants in the mini star party were placed near a tavern where there was a bit 'of unobstructed area from the snow.
The fearless are the order of the diameter of the telescope
winner: I myself with the leviathan from 60 cm.
Secondi classificati ex aequo: Tommaso e Fabio, con due dobson da 40 cm.
Quarto classificato: Andrea, con un dobson da 30 cm.
Quinto classificato: Pierpaolo, con un CPC 8" goto (orrore un GOTO nella tana dei puristi!).
Ultimo classificato: Marco, senza telescopio ma abile allo scrocco dei telescopi altrui, con il grave demerito di aver portato un computer nella tana dei puristi (peggio del GOTO) ma perdonato per la sua abilità a rintracciare il più remoto oggetto.

La considerazione generale di questa, che è la quarta uscita con il 60 cm è: "la differenza è grande".

Ho esordito con un'occhiata alla Testa di Cavallo, visibile con filtro H-Beta a 142x, as a large bend in the edge of the borders nebuolsa not very accurate. You could not see the shape of the head but do not despair because I was looking in one direction a little 'polluted and height less than ideal.

The thing that left a mark at all is the way in which galaxies are seen. Almost all show details, spirals, stripes, etc..
M51 is literally "stratospheric." Observed from about 100x (with the eye 30 mm) to about 300x (with a Pentax 10.5). Too bad for seeing the vision otherwise would probably have been better than a 300x. The spirals are visible without any effort. Are not vanishing: indeed showed several reinforcements. You could sense offshoots of the halo in different directions, Follow the bridge between the two and see the break.

not mention all the observed objects. Only a few more thing to point out that you can see in the sky at 60 cm from a two tenths from perfect.

Leo I. The dwarf galaxy Leo. It 'an object of low surface brightness difficult to view because near Regulus. Regulus by putting off the brightness of the galaxy was evident, especially by moving the telescope. Once identified remained visible even when regulation entered in the field of view.

NGC 4631 (Whale). was seen as very bright. One can distinguish (unlike that in the 40 cm) several condensations in the galaxy main the companion and the enlargement of the head of the whale. The two interacting galaxies in the vicinity were as rich in detail.

M61 appeared to be resolved as a beautiful spiral. A small M101. And M101 is another object that has attracted the attention of all: The spirals could be seen throughout their course, with several condensations of stars and the deformed portion that extends from one side. We also saw dioverse field galaxies nearby.

the end product also M13. Apart from the clear difference in brightness and number of stars, this time the small galaxy IC 4167 was obvious, even as a template, while the NGC 6207 also show internal structure.


Notes Marco

The first thing to say is that I still find it very difficult to pick up the tall objects. The scale is not an issue to watch, but the point is, why do I have to look in the finder often lean too dangerous positions. However, the objects I've seen, in all instruments, were many: counting all individual galassiette are seventy. This is because many small galaxies are close to other noble and so are free. Points particularly to the Galaxy "lumps" at the Windmill NGC 5477, NGC 4488 and the bar near the M49.
The Sombrero was spectacular and seemed to me as I'd like seen in Namibia, but obviously the quality of the air and 10 cm difference (remember that there had to hire a 50 cm) were compensated a bit '. It also tells the little-known hydro NGC 3109, which is the most peripheral of the local group galaxy. It 's a long uneven brightness from very low, but large in size (20'). The chain
Markarian I spotted both with 40 cm with 60, even if in a hurry. Add
also a curiosity for the first time I used a planet as a starting point for the star-hopping, that I used as reference to find the Saturn beautiful M61. This is also a galaxy unjustly neglected, perhaps because it is a few degrees off from the 'crowded' main di Chioma-Vergine, ma è sicuramente più meritevole di molte delle singole componenti dell'ammasso.
Morale finale: con questo fantastico telescopio concetti come "visione distolta" o "intravedere" sono solo un lontano ricordo!

What Do Puppy Cataracts Look Like?

Galaxies!

L'uscita di ieri sera è stata un po' di fortuna. Gli impegni della mattina successiva non permettevano di restare fuori tutta la notte, e d'altra parte la Luna sarebbe sorta poco dopo mezzanotte. Così è stata scelta la destinazione del rifugio Carota.
Un po' freddino (meno 5) e cielo sottotono anche per quel luogo: intorno a 20.9 allo zenit (21.05 verso Nord Est ma 20.6 verso la pianura a Sud). Via Lattea invernale visibile imaginatively.
mates were out Mars4ever, Mk67, AndreaF, Maxbjo and a friend of whom I do not know nik. Third
light for the 24 ". There were also two SkyWatcher 12" in a autotracking.

I used a new version of the fan, I have suspended elastically to prevent vibration. Perhaps dovendola no longer maintain contact with the bottom of the telescope has lost efficiency, breathing air that does not come even from within the mirror box. The fact remains that arrived there (starting at about 15 degrees at home) optics gave us a lot 'to work fairly soon. At first, the stars were balls, and also just inguadrabili 100x to 285x. The view has improved gradually but not è mai stata perfetta. Non ho potuto però fare tanti esperimenti perché le persone presenti erano curiose di osservare (e giustamente) nel 60 cm. Può anche essere che il seeing abbia contribuito (comunque la soluzione della ventola ancora non mi soddisfa del tutto).
Nei due Skywatcher le stelle erano puntiformi, ma è anche vero che usavano tipicamente ingrandimenti più bassi.

Abbiamo osservato circa una ventina di oggetti. In un cielo che non sarebbe stato da galassie le galasssie l'hanno fatta da padrone. Ne menziono solo alcune, lasciando la lista completa al contributo di Mars4ever.

NGC2903 nel Leone, osservata prima in 30 cm e poi nel 60 cm. La differenza era "abissale" :-)... oddio... non si capisce vero? E allora ecco una spiegazione più chiara. Nel 30 cm la galassia appariva come una macchia ellittica su cui si potevano intuire delle irregolarità (le spirali e il nucleo). Nel 60 cm le spirali erano là ben visibili, si vedeva anche l'alone e si percepivano dei nodi di stelle in entrambe le estremità della barra.

M81 nel 30 cm era la solita visione sfumata di quando il cielo non consente di vedere le spirali. Nel 60 cm le spirali si vedevano e si vedeva l'alone più esterno. M82 era quasi molto intensa e dettagliata.

M51 aveva le spirali evanescenti nei 30 cm, che si sono trasformate in bellissime spirali nelle quali si potevano notare diversi ingrossamenti avvolte nell'alone della galassia. La compagna showed memory structure including the black wedge that is inserted in the galaxy alongside the alleged bridge of matter. It would have been to do a drawing (which would have required but mezz'roa driving force in stages would not allow it). Always very nice

M96, M95 and M105. Typically, magnifications used were 213 (Pentax 14) and less often 142 (Pentax 21) and 93 (ocularone China by 32 mm). We also tried a 35 mm eyepiece of Andrea, with whom I'm definitely over the pupil, but has made a good overall picture of, M81 and M82.
The site is polluted enough that I have found it convenient to use a filter to broadband (a IDAS LPS).

Other items noted were several open clusters (Showing colored stars), NGC2440 is a planetary Vattelapesca, M3 (which has not been able to "explode" as the obsession with publicity, probably because of the difficulty to go with the magnification), and finally the Intergalacti Wanderer. The globular appeared to limit the possibility of resolution into stars (and we had the impression that probably seeing a better solution could be found).

Finally a decent evening. Nothing fancy (in theory was provided but there has graced Jet Stream). So here I am telling the true result of the second test of the Leviathan (the first high-resolution).

Yesterday I used a modified version delle ventole di aspirazione. La modifica consisteva in una sospensione elastica che nelle mie intenzioni doveva servire a isolare dalle vibrazioni la ventola. La ventola è di diametro generoso ed è evidentemente sbilanciata, al punto che mi ero accorto che li immagini stellari ad alto ingrandimento venivano strisciate (forse un paio di secondi d'arco). La modifica non ha funzionato (quindi ci devo pensare meglio) Per fortuna la temperatura esterna era mite ed è bastato il tempo di ventilazione da prima di cena al momento dell inizio delle osservazioni (più di un'ora) per raffreddare lo specchio quanto basta.
La soluzione non era ottimale ma poi abbiamo osservato senza ventilazione (di tanto in tanto una ripassata).
Il seeing era medio. 18 SQM. At times cloudy skies and fog that has intensified after midnight. The fog had certainly the effect of reducing contrast and definition (at one point saw muffled even the roof of my house).
station in the back of the house in the country.

The telescope continues to be ade a bit 'hard movements. I plan to spend the teflon spray on the motion to adjust the height and azimuth movements. For the second aspect has to be said that the telescope has a central pin and the three classic shoes teflon. However, the center also has a bearing that supports the weight of the telescope by downloading some of the weight and friction on skates. By adjusting the position of the center pad can adjust the load on shoes to adjust the hardness in azimuth.

moved to the field test. It was me, Maxbjo and Mars4ever. In addition to the leviathan of 60 cm was the GSO 8 "and Geoptik 19" in EQ6 Mark (with a lot of photography equipment in high resolution). Before dinner

Mars was a orange blob. But after dinner, you may stop the fans because the mirror was "decently" in temperature, the image of Mars was beginning to clarify.
In short, the Leviathan has exceeded in quantity and quality (more and better) the view from the GSO 8 ". The baby was struggling to be used at 320x. This figure is for comparison with other nights where the baby comes almost regularly 400x and January 23 480x.
The enlargements were used in the leviathan of 420x and 600x. Although the seeing is not a good telescope with this diameter (and with the optical quality of which I will) has no problems. The effect of seeing is to see the image as if through a soft filter, but you can look, while at other telescopes that are closer to their theoretical limit, due to the seeing the need to get with the magnification.
Among the details that I have seen mention clouds at sunset and that which at first I mistook for a small polar cap at the pole opposite to that of the big shell. Then Mark told me that it was cloudy there too.
Knowing that there was something in the opposite pole I have found in 8. "Mars was only 12" at 600x, but had a large planet that crossed the field of view.
I saw Solis Lacus as the usual series segnetto she "there is no" but just as a wink. Mark just put the eye to the telescope has also seen the Valley Mrineris (which I've also found later). With
Maxbjo has digressed to the Eskimo, which has a cielop between 18 to 333x and 600x magnification showing the two shells and the central. Try the OIII and UHC filters.
We also passed by M35, with 21 mm eyepiece to 142x (which is the minimum magnification that I can do for the moment): The storage occupied the entire eye field and the stars at 142x were colored pinheads. More
Later that night I had the opportunity to experience pinpoint stars up to 333x, 420x and 600x to even the faintest stars tended to flash depending on the seeing (which I repeat was not exceptional).
Back to 142x on Mars the planet was stuck in the sky. Some would say or carved marble. But 142x is a bit 'just to see everything there is to see. Also pulling his eyes, although we saw that there were structures on the planet, it took no great effort of imagination to understand that they form, the form that is revealed along with a multitude of other details by going to 420 and 660x.

Max is gone and Mark in the meantime had begun to take pictures. I could compare the view in the 10 " with the view in the 60 cm and, of course, and how physics provides, there was a real gulf of difference. Neither more nor less than they should be. And of course, looking good, was not even true that the image in 60 cm was more ballerina. Indeed it was almost the opposite (also this thing actually exactly predicted by the theory).
In the meantime, had come to view the area of \u200b\u200bvolcanoes. The face of "boring" of Mars, but in 60 cm so it was not boring at all. You could see several spots of different color. I tried unsuccessfully Olympus Mons I saw several lighter areas. IUL detail was such that we had difficulty drawing it.
We got to observe the color filters. In filtro Blu si poteva riconoscere la struttura delle nuvole, che corrsipondeva bene con le zone di colore più chiaro in luce naturale. Dunque stavamo vendendo anche ne nuvole più deboli. Quando Mars4ever ha terminato le sue fotografie, guardandole, devo dire che la visione nel 60 cm non era poi molto meno del risultato DOPO lo stacking delle foto (ancora sui colori seprati). Dalle foto è stato poi chiaro che l'Olympus Mons e gli altri vulcani non avevano delle nuvole sopra ma erano contornati da nuvole. Quindi i vulcani erano in corrispondeza delle macchie più scure che vedevo.
Il filtro rosso è stato un'altra rivelazione: finalmente un Marte luminoso anche nel filtro rosso, abbastanza da poter leggere tutte le strutture superficiali senza straining the eyes and imagination.

two o'clock I had a look of Notre fleeting Saturn. Net and "marble" but uninspiring saw cutting. You could see some bands on the globe, but perhaps also because the cutting, lacked the variety of colors that I remember (especially the brown at the poles).
