Title M8 and M20, with Stars in Original Palette

Description The Foraxx palette stars seemed off to the blue, so I extracted the stars from my original image, after DBE and BXT but before splitting channels. I ran SPCC, gave the image a gentle stretch with the midtone slider in Histogram Transformation, and then re-screened them to my starless Foraxx image of the nebulae. Better or no?
