The above image was taken on November 28, 1999 from Sooke, BC with Cookbook 245 LDC CCD camera on Celestron Ultima 8 f3.0 telescope. The whole setup was autoguided with Cookbook 211 LDC camera on a piggybacked 500mm f8 telephoto lens. White integrations (8 x 240 sec.) as well as cyan, magenta and yellow-filtered exposures (4 x 240 sec. each) were combined with AIP4WIN. Color image was then further processed in Lab color space using Corel PhotoPaint 8.
