Description

After stacking, I removed the stars from each HORGB master, cleaned up the data using GraXpert AI and RC Astro NoiseXTermiator .
Next, I processed the starless nebula data using LRGB combination to add Ha as Lum to the Red channel and Oiii as Lum to the Green channel and then just the Blue data by itself.
These were then combined using Channel Combination to produce the RGB nebula image.
After stretching I used both Red and Cyan masks on the nebula data as I applied Local Histogram Equalization, HDR Multiscale Transform and then Unsharp Mask to the nebula only data.
I then recombined The nebula data with the stretched SPCC RGB stars using Pixel Math.
