The above image was taken on July 12, 1999 from Sooke, BC. Cookbook 245 LDC CCD camera was used on Celestron Ultima 8 f6.3 telescope autoguided with Cookbook 211 LDC CCD camera on a piggybacked 500mm f8 telephoto lens. Eight white exposures (120 sec. each) as well as cyan, magenta and yellow-integrations (4 x 120 sec. each) were combined in AIP4WIN and the resulting color image was further adjusted in Lab color space with Corel PhotoPaint 8.
