NGC4038/9 Reprocess by the Yowie

I had taken this data a couple of years ago with the 200mm (8") f/6.9 prototype Newtonian that I built prior to building my current 12.5" scope, and decided to reprocess the data to see how much I could improve on my original efforts. I've also decided to give that scope a name (Yowie) in keeping with the theme for my current scope (Bunyip)

There was a fair bit of noise in the data and very little green:
LRG(G)B - 2.5hrs Lum, 1hr Red, 1hr Blue, 30mins Green + R+G simulated Green. My starting point for the reprocessing was the combined (Mean) and aligned L,R,G,B .fit files.

Thanks for looking.
