Description

A beautiful area of the skies full of galaxies of different size, shape and orientation.
I used my a similar PI workflow like on the images of NGC 2903 and NGC 4228 including the following steps. Any input to improve is welcome
Linear range
  • DynamicCrop
  • DBE
  • SPCC (still having a slight green cast after SPCC)
  • Repaired HSV Separation script
  • Deconvolution (PSFImage, AdvStarmask, luminance mask)
  • MMT noise reduction and removal of black pixels

Stretching:
  • MaskedStretch
  • NoiseXTerminator with standard stettings
  • Arcsinh + HistoTrans

Finishing
  • NoiseXTerminator with standard stettings
  • HDR with GAME mask over Gx
  • LocalHistogramTransformation with GAME mask over Gx
  • MorphoTrans on stars to reduce size
  • CurvesTransformation with different masks for colour saturation, background reduction, star colours ...
  • MLT sharpening
