Description

This has been one of the more challenging images I have done so far.  The data is great, but getting good colors and details takes a lot of work.  I started over in the processing about 5 times over a span of 3 weeks and finally got something I liked.

I used a mono camera (ASI2600mm) for the SHO channels, and some short exposures on a ASI2600mc color camera to get the star colors. -I was amazed with how much nebula signal there is with only 45 s of integration, I made the version C image the color camera version with only ~34 minutes of exposure. 

I also tried and compared the new startnet++ V2 AI models and StarXTerminator model to separate the nebula and star images for independent processing.  I thought StarXTerminator did a better job at removing all the stars, but it left a different noise pattern behind that was hard to process to make things look uniform.  Starnet didn't get all the stars and had residuals, but I could clone out the artifacts.  So at least for this image, I liked Starnet V2 better.
