Coma Cluster processing help needed

I thought I was on a roll, with a couple of reasonable LRGB images under my belt.

Sadly it has all gone a bit off track.

If anyone has time would they mind having a look at the stacks - I've aligned them and cropped to the reference frame, so the files are smaller now.  The total integration time is 8 hours.

Here it is - simple RGB ratio + gamma 2.2 (no color calibration):

Quite dull looking? It turns out - most of these galaxies are indeed just yellow / orange-ish.

Btw - very nice data set.

Thanks Vlad.  The image blows my mind, so many galaxies.

Fascinating landscape of galaxies captured in that frame, brilliant.

I've not brought in as much colour as your initial image, but did the basics - background extraction, RGB combine, colour calibration, SCNR, small-med stretch of each, LRGB combine, cosmetic tweaks (colour, bright stars).

It's the solved image that really highlights just what's in the frame:

Thanks for sharing the data.
