Neat little pinwheel with some nice details. Dare I ask how many bazillion light years away this might be?

The Pinwheel Galaxy (M101) is a spiral galaxy 21 million light-years from Earth and is about 170,000 light-years across. It contains an estimated 1 TRILLION stars, 5-10 times more than in our own Milky Way.

Hey Bill, this is awesome! I have been missing your astrophotography so it’s really awesome to have you post these new ones.

M101 is one of my favorites, and you did a great job with it.

That is such a pretty galaxy, Bill.

Lovely target, you have brought out some nice details, including the pink star forming regions in the arms. Super job on this one!
