Description

Fortunate clear night during New Moon and I felt a need to get out of the house. Still, data is lower SNR than I'd like. Simply can't compete at F/5 on these types of objects 

PreProcessing:
 - Darks, Flats, Flat Darks calibration
 - Subframe Weighing
 - Star Align, Comet Align
 - Batch BlurX + StarX on CA
 - Comet integration
 - Comet subtraction from SA
 - Star/Background Integration

Housekeeping:
 - Crop
 - DBE
 - Channel Combine RGB
 - ColorCalib on starless Comet image

Starless Comet Processing:
 - ColorCalib
 - CloneStamp for star/galaxy remnant removal
 - PM to fix streaked Comet nucleus
 - Rista TGVD, MMT
 - RGB: ASH+GHS
 - L: GHS
 - Rista ACDNR
 - L: additional Masked Stretch
 - L: HDRMT

Starfield processing:
 - ImageSolver + SPCC (RGB)
 - BlurX
 - StarX > CloneStamp Comet remnant > PM Star Screen
 - Rista TGVD, MMT
 - RGB: ASH+GHS
 - L: GHS
 - Rista ACDNR/MMT
 - PM Screenblend Comet into starfield
 - Pulled RGB_L and blended into L to ease LRGB Combination transition

 - LRGB Combination
 - Curves contrast, vibrance tweaks with star, galaxy, comet masks
 - SCNR > Inv > SCNR
 - Bill's SR
 - Final Crop
 - MMT for tail color noise
 - Annotation
