Messier 81   HOME INDEX BACK NEXT
 

Galaxy in Ursa Major. Messier 81 is a beautiful spiral galaxy, one of the nearest to us. At magnitude 7, it can be seen fairly easily with binoculars, but all that can be seen is a faint oval patch of light. Even through very large telescopes, the intricate details in this photograph cannot be seen visually.

Image details:  25 exposures, each 300 seconds at ISO 1600, taken with a Canon 400D camera through a Meade 12” telescope at f/5.4.  Image processing with ImagesPlus and Photoshop.
