M101; Pinwheel Galaxy

This is another part of my two-night project. In both nights I started with M65&M66 and after 3-4 hours of imaging continued with this one.

This can be found in constellation Ursa Major and lies about 27 million light years away. With a diameter of 170000 light years it's nearly twice the size of the Milky Way (our own galaxy).

Picture have a total exposure of 5h 35min (L=8*10min+9*15min, RGB=8*5min each, bin2*2)
