That’s a really interesting image in SHO. Have to say I think I prefer the RGB but still a worthwhile effort. By the way- the full scale image is wonderful and those stars imho are pretty darn good for an sct. Guess that’s the advantage of the edge. I agree APP does a wonderful job for stacking, gradient removal and colour calibration. In PI do you do the photometric colour calibration? I found that it does a pretty good job and possibly introduces a bit less noise than APP colour calibration.
