M108 = NGC3556 ( 11h 11.5m +55°40´, 10.0 mag. )
This small spiral galaxy in Ursa Major was discovered by Mechain in February 1871 or 1872. It is about 46 million ly distant and it is "choking" with star forming regions and dark dust clouds. It resides very close to the Owl Nebula (M97) and both fit nicely together in the same low power telescopic view.
The above image was taken on April 15, 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 piggybacked 500mm f8 telephoto lens. Eight white exposures (240 sec. each) as well as cyan, magenta and yellow-filtered integrations (4 x 240 sec. each) were combined with AIP4WIN. Color image was then adjusted in Lab color space using Corel PhotoPaint 8.
