Description

Processing
  • Preprocessing using WBPP
  • SubframeSelector > ImageIntegration > Drizzle Integration
  • DynamicCrop + DBE on individual Ha/Oiii/Sii channels
  • LinearFit all channels to Sii
  • PixelMath to create color image with R=0.7*Sii+0.3*Ha / G=Oiii / B=0.9*Oiii+0.1*Ha
  • BackgroundNeutralization + ColorCalibration on RGB image
  • PixelMath to create L image with avg(Ha, Sii, Oiii)
  • TGV + MMT for denoising on L image
  • 2x ArcsinhStretch + HistogramTransformation on both RGB & L
  • 2x LocalHistogramEqualization on L channel
  • LRGBCombination to combine L + RGB images
  • Curves for color balance, saturation, and contrast
  • Star reduction using MorphologicalTransformation with a contours mask.
