Reprocessed NGC 4038/4039

So, I'm modifying my processing workflow (in Photoshop) to account for my new processing toys; StarXterminator and NoiseXterminator! Apologies in advance for boring you with another repro.

I always knew there was more depth in my 2016 data but couldn't reveal it effectively because of noise. My new toys removed the noise limitation and improved my ability to work on the galaxy (sans stars), and stars (sans galaxy). For this image I reprocessed my Lum and RGB masters, then combined them (all in Photoshop). The result is more faint extents and more faint stars. I was able to improve some of the colours in the body of the galaxy too, but they're mostly the same.

Below is the old version (Left) and new version(Right).
