ASTRO: Butterfly nebula (IC1318)
The next time I used the Skywatcher ED80 with the QHY8/Astronomik UHC
combination to image the Butterfly nebula around Gamma Cygni. 7x20 minutes were all I could get in one night. Taken from the middle of Berlin with a Skywatcher ED80 at f/5 on a G11 mount, QHY8 camera with Astronomik UHC filter, 7x20 minutes. The picture can also be found at http://ccd-astronomy.de/temp2/GammaC...20smallgut.jpg Stefan

Never used such a corrector so just a guess. These are good targets for you OSC. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh".
