M51 with data from April 25 and May 1 for more than five hours of exposure. 60 three minute exposurs and 26 five minute exposures drizzle stacked and HDR composited. I used StarXTerminator to separate nebulosity and star layers, enabling optimized processing to bring out the best details in both. I also used localized stretching on the brightest stars to control star bloat.

Imaged on 2022-05-01 and 2022-04-25. A total of 86 three or five minute exposoures taken 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, StarXTerminator, Topaz DeNoise, and Photoshop.
