M101 is a beautiful face-on spiral galaxy distanced 21 million light-years away from earth in the constellation Ursa Major (wiki). I have tried to take a picture of the Pinwheel Galaxy several years ago, with a smaller refractor and DSLR. And after 2 years with my 20 cm Newton it came time to make it better..
