M101 in Ursa Major.  TEC 140 refractor, ATIK 460 and Astrodon LRGBHa filters.  Pixinsight and Photoshop processing.

Five hours of ten minute luminance 1x1, 90 minutes each of RGB 2x2 and two hours of Ha(3nm) 2x2.

March 2019 for Luminance and April 2020 for everything else. 

I'm happy with the galaxy but I could not control the two three upper stars.
