Description

Decided to try heading out to a local trailhead for from darker skies to try them out. Worked out pretty well.

Pretty standard processing which worked out well since the data was much cleaner than I usually deal with.
  1. WBPP
  2. DrizzleIntegration
  3. DBE
  4. PhotometricColorCalibration
  5. RGBWorkingSpace to (1, 1, 1)
  6. TGVDenoise
  7. MMTDenoise
  8. SCNR (Green 0.4)
  9. CloneStamp to fix up some weird star cores
  10. RepairHSVSeparation to fix up additional weirdness in star cores
  11. Split L channel
  12. LHE (512 / 2 / 0.25) on L
  13. MorphologicalTransform with Erosion and a range mask on the brightest stars to tighten up the cores
  14. MorphologicalTransform in Selection mode + Contors Mask to reduce stars slightly
  15. LRGBCombination
  16. DarkStructureEnhance
  17. Curves for saturation + contrast
  18. MMT to reduce additional chrominance noise
  19. Light UnsharpMask
  20. IntegerResample to downscale by 2x
  21. Curves for days
  22. One final round of DBE to reduce some final gradient
