Description

This object was an incredible challenge to process, and I am glad to have attempted it! I have photographed only one comet before, which was 21P/Johnson back in early 2017, so I knew this one would be even more of a challenge in LRGB. Part of me still wishes I would have simply used my T3i for some simpler processing, but I am heavily tempted by the cooling in the 1600MM-P. 2023 reprocess unfortunately couldn't bring out as much of the faint red CO tail but overall the quality still seems better to me

Preprocessing:
 - Darks, Flats calibration
 - Subframe weighing
 - Star Align, Comet Align
 - Batch StarX of Comet Aligned images
 - Starless Comet integration
 - Subtraction of starless Comet from SA images
 - Star Background Integration

Housekeeping:
 - Crop
 - DBE
 - LFit R, B to G
 - RGB Combine

L Processing:
 - BlurX
 - Rista TGVD, MMT
 - Masked Stretch
 - Curves contrast tweaks
 - Screenblend Comet onto starfield

RGB Processing:
 - ImageSolver + SPCC (Stars)
 - BlurX
 - Color Calibration using previews (Comet)
 - StarX > Clone Stamp out Comet/Star remnant> Screen Stars (as applicable)
 - Rista TGVD, MMT
 - ASH (Comet)
 - ASH + GHS (Stars)
 - Rista ACDNR
 - Screen blend Comet into Stars
 - SCNR > Inv > SCNR on stars

 - LRGB Combination
 - Vibrance / contrast tweaks in Curves
 - Annotation
