M81 shares a cigar with friends

Five Galaxies in Ursa Major. Left to right: the Cigar Galaxy (M82), Bode's Nebula (M81), NGC3077, PGC28731, and NGC2976. All spiral galaxies about 12 million light years away. This image was shot from my driveway in Austin, Texas, the morning of 2021-03-15, under a Bortle 6-7 light dome.  RedCat 51 f/4.9 250 mm telescope, Baader UV/Skyglow filter, and ZWO ASI533 MC Pro camera.  Capture controlled by a ZSO ASAIR on a Sky-Watcher AZ EQ5 Pro mount with a ZWO mini guide scope and camera.

21 3 minute sub exposures for a total of 63 minutes total exposure at unity gain and -10C. Images stacked and processed in PixInsight, and Topaz DeNoise, with final crop and exposure in Photoshop.
