I have mentioned it before Doug. This is a fuller explanation. GradientXterminator is fine if you have a galaxy or nebula in the center of your frame. You are in deep trouble with faint nebulae all over a widefield. Sure you get rid of gradients but you also lose faint nebula detail as it looks like gradients to the program.
What I do is split the colour image into RGB fits and then make R,G & B tifs of each. PS has not got a clue about fits images. I then treat each monocolour tiff with GradientXterminator in the usual way.
The advantage now is you can isolate real faint nebulosity from gradients and GX does not fart around with the other colours. I do not know what his algorithms or protocols are but this eliminates unwanted suppression of real faint nebulous data. Each image has its own method that you must work out by trial and error. It pays to be consistent with the RGB for the same image for Detail and Aggressiveness and only vary the areas with the Lasso tool.
Hope this helps. Any futher questions?
