Bode's Nebula M81 Revisited

Bode's Nebula, M81, and the Cigar Galaxy, M82, are about 12 million light years away. This is a more rework of my data from last week. There are some very faint satellites of M81 just visible in the image. Thanks to Akarsh Simha for pointing this out. Holmberg IX (UGC 5336) an irregular galaxy is above and adjacent to M82 (11:30). Another, PGC 28731 is a faint spiral, a bit further away (9:30). You may have to up the brightness of your display to see them in the full size image linked from below. Credit to Topaz DeNoise AI for pulling these out of the noise with only 1 hour of data. The Hubble has taken a much closer look at Holmberg IX.

Because of thin high clouds, I was able to use only an hour out of the three hours of data, with 20 three minute exposures stacked in the final image.

Taken 2022-04-27 04:06 UT from Fort Davis, Texas, with a William Optics RedCat 250/51mm telescope, Baader UV/IR cut filter, ZWO ASI 533 MC camera, and SkyWatcher AZ-EQ5 mount, ASI EAF and guide camera. All were controlled with a ZWO ASIAir Plus Controller. Processed in PixInsight, StarExterminator, Topaz DeNoise, and Photoshop.
