Description

My first HDR image. I combinded 10 images each taken at 60s, 120s and 240s. I guess this is my best M42 so far.
Processing in Pixinsight was done by registering all images together and making 3 master files, one for each exposure.
The 3 masters were cropped and  combined in the linear state using HDRComposition. Then the normal processing followed:
  • I missed ABE or DBE, because it was impossible for me to define the right background points
  • SPCC
  • Repaired HSV Separation script
  • BXT (Deconvolution was resulting in too many artifacts)
  • MaskedStretch
  • GHS, HistoTrans
  • NXT
  • StarNet2
  • starless image
    • further streching
    • HDRMultiscaleTransformation, 50:50 blended in pixelMath with original image
    • LocalHistogramEqualization

  • Star mask:
    • MorphoTrans

  • PixelMath to combine both images
