Since the frame contains both hydrogen and dust in various forms (bright and dark), I decided to go with an honest RGB approach.
There were many attempts to fit the huge dynamic range into the modest capabilities of screens, without losing detail in the dark nebulae or blowing out the bright areas. The task is complicated by the vast number of background stars typical of the Milky Way.
In the end, something did come out of it.
