ASTRO: NGC 55 from Namibia
I spent the last two weeks on astro holidays in Namibia. Unfortunately the
weather wasn't as good as I had hoped it would be with only four fantastic nights in two weeks (and 2 or 3 partly clear nights). Even though nights were about nine hours long I only managed rather short exposure times for the two objects I imaged in each of those clear nights. The reason for this was that I had to fight the traps and pits of the rather abysmal "Starbook" attachment to the Vixen New Atlux mount I hired for my stay. The mount itself was good (except for a very large backlash in dec), but the Goto controller (Starbook) really cost me a lot of time. In one of the partly clear nights I used my QHY8 camera to image NGC 55, one of our galactic neighbours. Taken from the middle of Namibia ;-) with a 10" Meade ACF scope at about 2100mm focal length (AP reducer) on a Vixen Atlux mount, QHY8 camera, 7x15 minutes resized to 66%. The picture can also be found at http://ccd-astronomy.de/temp3/55-7x15smallgut.jpg Stefan |
