It’s been a long time since my last effort on an LRGB target. The Markarian’s Chain was a quick test (only 3.75 hours LRGB) at SPAC Dark Site.
The luminance channel lacks data and it’s a big headache to process. Lots of local adjustments made in both PixInsight and Photoshop. I am happy with the final result for only 3.75 hours of imaging.
