M101 the “Pinwheel galaxy” is a spiral galaxy in the constellation Ursa Major.

This is the first image with the new setup (CFF135 telescope +AP1100 + QHY268M), I am impressed with the level of details the CFF was able to resolve in the galaxy despite the small scale and the very limited integration time (5hrs total) LRGB. I added 2hrs Ha to enhance the emission regions.
