M20 - First LRGB and First Light on Target

Hi all

A fun first attempt at LRGB imaging and a new target for me. I know it's a popular target, but I've never shot it before.

A little noisier than I'd like, and not as much detail as I'd hoped. Thankfully, stars don't go anywhere and I'll add to this over the coming years. This would be fun to shoot with a much longer f/l scope.
As it stands, this is a relatively heft crop of the 268M + Esprit 120 FOV.
I've got loads of tilt to sort out though, but heck it's still fun to get a final image.

total 4 hours integration from a B6 backyard (parents house!)

L = 30 x 180
R = 17 x 180
G = 17 x 180
B = 16 x 180

QHY268M, Antlia Pro 3nm LRGB
Captured with NINA (2.0 release is utterly incredible)
Esprit 120 + 1x flattener on EQ6-R

Processed almost exclusively in PixInsight and finished in PS.

PI: (WBPP > Star Alignment > channel combination for RGB -> Dynamic Crop -> DBE -> PCC -> Denoise and Decon on Lum, Denoise only on RGB > EZ Stretch > Curves Transformation on RGB > EZ Star Reduction on L > LRGB combination > EZ Star Reduction on LRGB final)
PS: Black levels.

Thought about Topaz, but it didn't do a great job with this image (sometimes it does, sometimes it doesn't)

As always, a link to a bigger version can be found here

And as I've created an Astrobin account, I'll link to it when this image is up for those of you who prefer that.
