Orion Nebula - M42 - LRGB HDR
60 sec LRGB, 5 sec additional L for the Trapezium, ~5hrs total integration (LRGB).
Also captured some Ha around same time so will try adding that separately.
This is an improvement on last year's OSC (APS-C) version, which was noisy with much less data, but I liked the colors:

Unfortunate microlens effects using the ASI1600 here, especially on Hatysa. I was also fighting poor tracking on my CGX which now seems to have gone haywire, putting me out of action while I try to figure out what's going on. Don't look at the star shapes and color registration too closely!
Update (revision B)
Ha additions didn't work well (on either R or L) without better masking on Hatysa which I don't have time for, so just tweaked the colors and contrast a little on the original and refined the crop to call this heart-like nebula done for Valentine's Day!
