1. Gradient Removal via GraXpert
2. Combine RGB, AutoColor for Color Calibration (PI)
3. Prepare RGB for PhotoShop in PixInsight (BX for Stars, 1x low HT-stretch; 1x high HT-Stretch (1x starless)
4. Prepare Lum for PS (same as RGB but BX also on non-stellar stuff and higher HT-stretch for IFN)
5. Blend low-stretched Lum into high-stretched Lum in PS to restore Galaxy Details
6. Curves, Camera Raw Filter, Denoise… to get more of that IFN out of the Lum
7. Load RGB low stretch, high stretch and starless together to conserve most colors and have fine control over the stars
8. Color denoise and sat increase via Camera Raw Filter
9. Add the processed Lum as Layer with Blend Mode Luminosity and adjust it Curves so it blends well together
10. Create a heavily denoised RGB to enhance colors in color noisy areas (needed due to the short integration time in each R G B channel)
11. Enhance IFN via even higher stretched Lum with High Pass Filter
12. Final Adjustments via Camera Raw Filter
