I have seen many images of the Trifid and Lagoon where the stars have no colour because they have saturated the detector beyond it's dynamic range to image the really dim bits of nebulousity and dust.
If you all look carefully my stars still have their intrinsic colour.
Imaging widefields has a problem and that is very high dynamic range.
In my own way I am trying to address this problem.
Do not get upset if my opinion differs with yours. I just gave my best opinion.
