Does anyone have any best practices for stretching astrophotography images captured using a City Light Suppression (CLS) filter in rnc-color-stretch? I'm currently using Deep Sky Stacker for stacking to generate a TIF; however, as expected, resultant image pre-stretching has a strong blue tint with reds almost non-existent. My gut tells me I will be using the -setmin and -rgbskyzero flags but I'm very much a novice with this software.

I use the Astronomik CLS filter but use Astro Pixel Processor.

Are you loading flats, dark flats, darks, and bias frames along with your lights?
