So the answer is: set Nebolisty's Color file format in preferences to RGB Fits: Maxim.
So now I see I have some hot color pixels - Guess I need to retake my darks, etc.
All I can say, is thank you so much for helping me through this. I was regretting spending the money for ST, but now I am convinced I did the right thing. I have SOOOO many old pictures to go and redo. I've saved everyone of the "final" images (those that were pre-processed in Nebulosity before stretch, etc) that I've taken over the past couple of years. If we ever meet - I owe you a beer/wine/drink of your choice.
Ha! Now we're cooking with gas! Excellent coloring and you got the Bubble nebula - nicely done!
