This is M1, with a bit of a hack Photoshop processing job with a lot of destructive edits, just to see what kind of data I have. I'm going to work on it more carefully in the future. Fair transparency with Bortle Orange skies.

TEC 140 mm apochromatic refractor
Astro-Physics Mach 1 GTO mount
Gary Honis modified Canon T1i
Astronomik CLS light pollution clip on filter
17 X 5 minute subs, dithered
Calibrated darks, flats, dark-flats, and bias.

Stacked with Deep Sky Stacker and a quick stretching with levels and curves in Photoshop with the saturation boosted just a little. Color balanced with Gradient Xterminator.

I understand very little of what you wrote, but it's a nice image. Welcome to CQ!
