NGC891 in Andromeda

EXPOSURE DATA: TAL 150 PM telescope 150mm f/5 Newtonian telescope on a Vixen SP mount, Starlight Xpress MX5-C, 97 x 40s, 32 selected, taken November 4, 2004 from my backyard in The Hague, Netherlands. Although the weather was quite bad the days before and after, November 4th showed a break in the cloud cover after the passage of a cold-front. Fortunately I had the opportunity to go out that evening. I had my 80mm f/11 refractor installed on the Vixen SP as well. It helped a lot during targeting. A side-effect was the extra load on the mount, wich strangely enough reduced periodic error! I nevertheless had to discard 2/3 of the exposures because of clouds and an autoguider-experiment.
