This is the wonderful spiral galaxy M81, in Ursa Major. It was discovered on 31 Dec. 1774 by J.E. Bode. Its distance in estimated in 12 millions of light years.
Here, it was imaged with the Planewave 17 unit, part of the Virtual Telescope Project. A total of 34 exposures, with 5 minutes of integration each, were averaged. Images were unguided, completely trusting the Paramount ME mount. The CCD camera is a SBIG STL-6303E. The image scale is of 1.3″/pixel.
