Description:

Despite its magnitude of 8.5, M101 is a difficult target due to it's low surface brightness. At 170,000 ly across, The Pinwheel is a large face-on spiral galaxy in the constellation Ursa Major covering almost 1/2 degree of the sky. Pierre Mechain discovered this galaxy in 1781, and Charles Messier verified its position. He then added it to his catalog as one of his final entries.
