Hi Billx, I use Pixinsight.

After doing a drizzle integration.

Used ABE to remove the background gradients. After cropping any stacking artifacts.

Photometric CC

MSLT with the built-in Lum mask to remove background noise

Histogram Transformation to stretch to N-Linear

Make a Star Mask and Range Mask, subtract the Star mask from the range mask using Pixel Math

Use this mask to protect everything but the Nebula itself.

Apply LHE to bring out more details.

Apply HDR to bring out more core details.

Curves to tweak the color and brightness

Then using just the star mask MT to reduce the stars a bit

Then use a Lum mask inverted to protect everything but the background. And tweak the color a bit to get it the correct tint.

Then using ACDNR with its built-in Lum mask I slightly denoise the background

         I am no expert at Post Processing, there are many better ways to process I'm sure. This is a workflow that I use from many different sources. It works well for me at this point.

Thanks for your input about my image!

Thanks Sydney! I really appreciate it. It's a little tricky to process to bring out the details in the core. I think I have achieved my goal though, at least for now! Lol!
