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).
