Description

The text immediately below is from the 2023 reprocessing. The original processing notes are at the bottom.

2023:
DBE
SPCC
BXT
SXT
NXT
GHS (GH, linear, GH)
NXT (needed a bit more noise reduction)
a few spots of GAME/HT to slightly reduce halos
LHE
Curves (contrast)
pixel math in stars

stars:
GHS

2019 Notes:

ASI294MC Pro @ -15C


63x120s



I had to keep the processing fairly simple to avoid bringing out background blotchiness.

Used Windorized Sigma Clipping rather than linear fit clipping for flats and darks and used 7 sigma rejection for darks.



Processed with:


Dynamic Crop

DBE

PCC

HT

CT - contrast & saturation

TGV

MT to shrink stars

CT
- contrast
plus some final touch up in photoshop



I'm not entirely happy with htis but I've been playing with it for more than a month so it's time to move on for now.

Title: 2023 Reprocessing

Description: I wanted to see what newer tools and more knowledge could do on some fairly marginal old data. A few things stand out:

- GHS is marvelous!
- especially when stars have been extracted
- don't try to extract every last possible detail (a common failing for me in the past)
