Thanks Neil. The ED puts the colours together quite well, but there has been some worth removing some fine green and magenta fringes.

 Well your Fine tuning has worked well. looks close to reflector balance to me. Better than my 70mm F12.8 Achro for sure

I usually do something like this:

  • Stack in AS!3 giving 2 x Red, Green and Blue panels (asi178mm + 80ED can't quite do the full disk in 1 hit)
  • Registax Waveletts all 6, with the same settings. Not going to 'crunchy'
  • Stitch the frames in Microsoft ICE and save out the 3 mosaic channels
  • Align those 3 in imPPG
  • Open in PixInsight and convert them back to greyscale
  • LinearFit the Red and Blue to the Green
  • LGRB combine - This should give a reasonable colour balance without a distinct cast
  • Curves Adjustment on Saturation to bring the orange and blue up out of the grey.

At this point, I'm able to spot the fringes clearly:

  • SCNR noise reduction with it's default settings to remove green
  • Invert the image and run SCNR noise reduction again, effectively removing magenta (inverted green)
  • Invert back, then off to Photoshop for polishing in Camera Raw
