This was supposed to be a HaRGB image but I had problems with my Ha stack. The reds actually came fairly well even without the Ha. My process:

(Pre-Process)

Stacking based on this process. http://www.lightvortexastronomy.com/tutorial-pre-processing-calibrating-and-stacking-images-in-pixinsight.html

(Post-Process)

Registered RGB to Lum.

Dynamic Crop of each image

(Luminance Process)

DBE

Deconvolution

Multilinear Transform with inverted luminance mask

Histogram stretch

(RGB Process)

DBE on each channel

Linear Fit for RGB with Lum as reference

Channel Combination

Photometric Color Calibration

MLT with inverted image mask

Histogram strectch

(Post-Stretch)

LRGB Combination

SCNR at 90%

Light ACDNR

Color Saturation with range_mask+star_mask to boost object and star color

HDR Multiscale Transform with lightness mask at layer 6

Local Histogram Equalization

Curves on both RGBK and Saturation

Morphological Transformation with star mask (3 iterations at 40%)
