A Memorable Night Despite the Moonlight, 2005/8/23Posted By Dave Mitsky |
Disclaimer: this post has both deep and shallow sky content.
As far as observing conditions were concerned, Wednesday night was easily the best of the summer and may well have been the best of the entire year. The transparency was so good that Tony Donnangelo and I were able to log some very difficult targets with his 14.5" Starmaster Sky Tracker Dob including the globular clusters Palomar 9 and Djorgovski 2 in Sagittarius, even though we were at one of our lesser dark sky sites. In the category of the shallow sky, we looked at 3 asteroids we hadn't observed before as well as Pluto and later the Moon, Mars, and Saturn. (Tony has seen 99 of the first 100 asteroids discovered.) Tony and I were also treated to some very brief auroral activity in the north around 10:00 p.m. EDT (2:00 UT).
The seeing wasn't bad either. Some detail was visible on Mars at over 800x, while magnifications in the 400x range provided very pleasing views. If only the Moon had not risen so early, yada yada yada! (The Milky Way was still readily apparent despite the moonlight.) Well, at least the two of us were able to make some use of the lunar presence by each discovering previously unknown sunset lunar light rays. Mine was in the crater Busching.
I don't have my taped notes transcribed yet so a more complete report will have to wait.
