Description

Messier M42, captured at the beginning of January 2022.
I was in the process of setting up my "new toy", a QHY 268C OSC on to my FLT98.
There's a lot wrong with this image so don't look too hard ;-)
I couldn't get the flattener to completely cover the image. I've subsequently changed to a TSFlat2.
There are no flat calibration frames. All a bit of a experiment at the time. Then I thought why not run it through PixInsight to see what's there.
Calibrated each group with darks (Mode 0 - 19x300s & 29x 30s) ( Mode 1 - 11x 300s) separately.
Cosmetic correction, debayer then starAligned the whole set.
Normalised Scale Gradient script .
DynamicBackGroundExtraction & EzDenoise script on the resulting image.
I used ChaoticNebula's LRGB workflow as a guide. Extracting the luminance & sharpening that. - Thanks for a great guide.
Adam Block's Star de-emphasis to drop the smaller stars into the background a bit.
