Description

Nice to see some of the faint blue outer nebulosity.

23 hours of data.   I collected over 50 hours total of R, G, B, L, S, H and O but ended up just using the RGB.  I didn't 
get any added value with the other.

My home-built scheduler had a bug and I ended up gathering 2.5 times as much R data as G and B :-\ !
R - 816 minutes
G - 256 minutes
B - 300 minutes

Data was collected in my backyard observatory between July 2020 and October 2021 using Voyager and a DIY scheduler.
I am running Voyager Advanced now, which has a built-in scheduler and is a very nice upgrade from my homebrew one.

Calibrated with Siril, stacked and post-processed in PI and PS.
No noise reduction was used.
Just RGB combine, PhotoColorCalibration, HistogramTransformation.
HDRMT and LHE.  Curves to increase color saturation and also to boost contrast in the B channel.
SCNR to get the Green out.
Bodoni tools in PS - increase star color and decrease star size.
