M81 Group

19:25 14/3/2007 UTC

This time of the year M81 group is high near zenith during evening hours. Weather was pretty decent and light pollution was not that bad in the high sky. M81 is very photogenic and very impressive also visually. It was easily visible in finder scope. The third conspicuous galaxy in this photo is NGC3077, in the upper left corner of the image. The photons captured in my camera sensor left the galaxy about 12 million years ago.
