This M13 represents 5.25 hrs of 60s subs, with a near-full moon, using:
iOptron RC6 + AP CCDT67 reducer @ 993mm focal length
QHY183C
Orion TOAG + QHY5III462C
CEM40
KStars/Ekos
Siril
ST8
Workflow for this version: Bin 50%, Crop, Wipe, Contrast, HDR, Decon, Color, Superstructure dim small, Superstructure saturate, NR
Notes:
Wipe: Earlier with these data I had been trying to go as mild as I thought I could get away with. Then I tried being quite aggressive and it seemed to make a positive difference.
Autodev: Turned Shadow Linearity down to 18% and bumped Detector Gamma up to 1.10
HDR: I had been using Optimize to keep from over-dimming the core, but this time I started with the Reveal preset then dropped Gamma Highlight to 1.10 and raised Highlights Detail Boost to 70%. This somewhat tamed the core while also brightening the stars (all the stars) without seeming to raise the background noise to an unacceptable level.
I have, as ever, several color variants. The one I'm posting here is toward the bluer-end of the variants.
