ATIK Color Horizon (OSC) camera and Hutech HEUIB-II filter with a Sky-Watcher 190 Mak-Newt (1000mm f/5.3) on a Celestron CGEM DX mount, unguided.
Processed in PixInsight, Photoshop and Lightroom. All subs were processed as 32 bit images.
The first image was processed from the Live Stacked image. The 2nd image was processed from subs.
Enjoy!

First off the galaxy is so faint the color cones in the human eye don't recognize it as having color, i.e.: it looks like a very white faint star.
But you are probably correct regarding the second image being close to true color, at least from this side of the Earth's atmosphere. Not too sure what it would look like without an atmosphere interfering?

Nice job of pulling in details.
I prefer the second image just because I’m more traditional.
Well done on both.

Both the same photons, just different methods of capture and processing. But I do agree with you on the 2nd image. I does, however, require some Ha response.
