The Pinwheel Galaxy M101 (NGC 5457) is a spiral galaxy in constellation Ursa Major. It is about 21 million ly away from earth. The apparent magnitude of this galaxy is ~7.8 mag. Therefore, this object is well suited for astrophotography with equipment like mine.
There is also a full resolution image of M101 available. UPDATE: I finally decided to put this picture into My Top Astro-Pics gallery.
