Ivo, my steps up till now have been -load image, screen stretch, bin to either 35-39%, crop stacking artifacts then-
develop to high 90's, some of the time I think I over 'develop' and the image from then on cannot be ' wiped' back to a nice neutral uniform background? Is this correct- what I want to do is max the galaxy signal but create uniform bg.
After develop I have tried with either wipe (no partial masks) or with a mask then processed from there.
NB I am using the TIF file from deepsky stacker not the jpeg.
