Hi Bob,
Thanks for uploading those screenshots. Here too, I cannot see anything wrong or constituting aberrant behavior.
On my color-calibrated monitor, the result from Wipe is very,
very far from a balanced or acceptable rendition, whereas the initial Color module result is starting to show important aspects correctly.
Stars in the Wipe module result are devoid of color, whereas in the Color module different color temperatures are visible, with blue stars notably present.
Areas strong in H-alpha emissions (
such as Melotte 15 in the center) show strong, deep reds without channel clipping. Pushing blue a bit more, you should start seeing subtle shades of purple where the blue light from hot young O and B-class stars mixes in with weaker Hb and O-III emissions. In the result from Wipe, they are any one's guess what color Melotte 15 is, as it is entirely washed out. The muddy brown/red color cast in the Wipe module is entirely a coincidence rather than the result of any procedure resembling color correction.
Even if you do not prefer the Color Constancy rendering responsible for the color recovery of the center shock waves, this mode is instrumental in making sure you got your balance correct. You can switch to Legacy mode afterwards and reduce the Bright Saturation to mimic the washing out if you wish. If you are sure the result is too saturated as a whole, you can, of course, easily reduce the saturation with the Saturation slider. Please be aware that consumer-grade screens tend to greatly oversaturate colors to make them "pop". After color calibration with, for example, a cost-effective x-rite Colormunki Smile, you will find correct tones are much more subdued.
Lastly, if you wish to use the Wipe result as a starting point, you should be able to use the Legacy preset, set Saturation to 100%, Bright and Dark stauration to Full, and all Bias parameters to 1.0.
