M20 Trifid Nebula - Quick, late edition...

...with dust donuts at no extra cost!

I've been acquiring some new gear over the last couple of months, and the other night I got to try some of it out. This image is the result of the first successful test run after sorting out various problems.

Gear:
G11
RC10 with 0.67 FR.
ZWO ASI1600MM-C
Xagyl 8 position motorised filter wheel

Images (taken at "Unity" gain/offset setting):
Bias: 50
Darks: 60
L: 15x60s
R: 12x60s
G: 12x60s
B: 12x60s

Processing:
PixInsight - just the basics. Although I did have to crop as I have some vignetting to look into, plus the corners don't appear to be flat.

Another view, not jpg'd: https://flic.kr/p/LQjbuA

Things I already know I need to do: Flat images; look into the vignetting; check the spacing with the reducer; take more subs per channel; experiment with the camera settings; determine ideal LRGB exposure times from the backyard.

Any comments, constructive feedback, etc welcome.
