A quick process in PI...
- MultiscaleLinearTransform noise reduction (linear mask) all masters
- Combine RGB (LRGBCombine)
- BackgroundNeutralization
- ColorCalibration with galaxy as white ref
- Stretch
- ACDNR denoise heavy on Chrominance
- Apply star mask and blur chrominance (ATWT remove layers 1-4)
- SCNR
- Apply clipped luminance mask: Curves boost Saturation
- Curves Hue: cyan -> blue
- stretch L
- HDR mask (clipped Lum mask, remove stars): LHE 0.5, HDRMT 7 layers, slight ATWT sharpen (small bias increase layers 1-3)
- Combine L and RGB (LRGBCombine)
- Slight contrast curve
- ICCProfileTransformation -> sRGB
Cheers,
Rick.
