M101, The Pinwheel Galaxy, is a wonderful galaxy in Ursa Mayor.

Here the latest result o the collaboration between me and my friend Luigi Fontana

The RGB signal was caught by Luigi with his ODK 12" and an unmodified Canon 6D
Since the unmodified Canon is nearly blind to hydrogen like I've added the H alpha signal, caught with a Williams Optics FLT 110 with my SBIG ST2000XM and a Baader H alpha filter.
