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.
