NGC6559 Nebula - near the Lagoon

I'm quite liking this mono thing That said, processing LRGB images is not as straightforward as I'd thought ... but that's what makes it fun ... apparently ... with a G&T in hand Soooooo as I continue learning the basics of mono imaging ... it's almost OCD-like atm lol ... I decided to image something other than galaxies after stumbling upon NGC6559 while trawling through Astrobin for ideas. It's a beautiful part of the southern skies and is located a little east of the Lagoon Nebula. This is my 1st attempt at processing the data and I'm collecting more L tonight, and some Ha too. This version is a bit rough (eg. my cropping was crap, framing isn't quite right!) but current details are:

EdgeHD 8" with 0.7 R, ASI294MM, Antlia LRGB
~7hrs 10mins total
L: 26 x 180s, 15 x 300s
R: 30 x 180s
G: 30 x 180s
B: 30 x 180s, 1 x 300s
Stacked in APP, edited in PI, finished in PS. Cropped.

Hi-res is here. Thanks for looking. Alex

PS I'm also setting up a NINA system for my SW120ED refractor which hasn't been used since Christmas. It was previously an Ekos/Kstars system (on a RPi4) which runs nicely but I wanted to try a miniPC (Mele 3Q). Should have it operational in the next few weeks wooo. Thanks for the tips John (Oska).
