This is my 1st real attempt at combining HaLRGB from my ASI1600MM. I tried several methods. This is Ha & R 1st, HaR & GB, then L & HaRGB. I tried Pixinsight and PS. My best results were in PS. I am just not familiar enough with PI yet. But I'm trying to learn. Lately my best results have been to start in PI and finish up in PS. I'm not sure what I can do about the disco pattern around AlnitaK.
