And now for something (not) completely different: M56

Only 105 minutes total. If I keep having clear skies near full moons I might add to this.
With my small sensor I do not have the FoV to include M56's possible companion (NGC 5053), so just a boring photo with the glob centered in the frame. Most of the Astrobin images I looked at reduced the star field, but I left it alone and did not visit the Shrink module. I also skipped HDR this time, given the much smaller apparent size, compared to M3 and M13.
RC6 @993mm, QHY183C. 210 x 30s at gain 5 (that's 50 to you ZWOers).
I was surprised when I got to the Color module. Normally I wind up reducing green quite a lot, around 1.9. But there was very little 'excess' green in this image. That makes me wonder - it's the same sensor. Shouldn't the color balance be generally similar image to image?
