  • Colour balanced - 12% more shadow cyan, 7% more midtone green and a 10% more highlight blue
  • A masked curve to liven up the neb
  • A masked curve to dim the background sky
  • An overall curve to brighten everything
Sorry, I'll shut up now!

Thanks for taking the time, Marcus, I appreciate it. I felt the original image was too flat, thanks to the usage of masked stretch, so I wanted a bit more contrast in it. But you're right, I lost background nebulosity.

I've done yet another version. This time I've used a combined histogram transformation with masked stretch, then added HDRMT and local histogram equalization. The colour is probably still wrong, and it might be over baked for some people's taste, but on the flip side, there's more contrast and more background nebulosity.

Cheers Greg!
