Howdy.
Been a while between images, so I decided to see what all this fuss is about with PixInsight.
Well, thanks to some great pointers from Houghy

, I now know and am addicted. Looks like Photoshop may be having a considerable sleep from now!
I have reprocessed about 2.5 hours of M42 in LRGB, QHY9M and Megrez 110 from November last year. I realize that it still isn't perfect and my processing skills are still developing, but I have to say that I am happy with where this one has landed.
I have given a comparison of PixInsight to Photoshop, so tell me what you think. Please be honest, I won't care if you make me cry with strong criticism, otherwise I wont get any where.
PixInsight with DBE, curves, masking for colour, etc.
