Markarian's Chain

Markarian's Chain is a string of galaxies from the Virgo cluster, the most prominent are M84 and M86. Taken in Fort Davis last Thursday during the Texas Star Party. I reprocessed this image using StarXTerminator to separate nebulosity and star layers enabling processing to bring out the best details and color in both stars and galaxies.

Imaged starting 2022-04-29 04:00 UT. I stacked and processed 60 three 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.
