M101 - Galaxy in Ursa Major

The spiral galaxy M101 is a beautiful, large, face-on spiral galaxy.
Several knots of emission nebulosity and star forming regions with NGC
designations can be seen in this image. M101 is of a notable non-
symetrical shape with its core being considerably displaced. Cepheid
variables suggest a distance of about 22 million light-years.
