Description

Preprocessing & Mosaic Combination:
 - Darks, Flats calibration
 - CC, Subframe Selection Weights
 - Star Align, Drizzle Integration (Hα only)
 - Star Align & Gradient Merge Mosaic


Housekeeping:
 - Crop
 - DBE
 - LFit R, B to G
 - RGB Combine
 - HDR Composition for RGB, Hα, Oiii to recover clipped detail


RGB Processing:
 - DBE
 - Photometric CC
 - HSV Star Repair


Luminance / Narrowband Processing:
 - Multiple passes Deconvolution targeting nebula and smaller stars
 - Downsample to match image sizes
 - Blended broadband stars onto starless Hα image to form Master Luminance
 - Rista method TGVD, MMT
 - Masked Stretch + HT
 - Another pass of MMT
 - Several passes Unsharp Mask
 - Final LNR using ACDNR


NB Combination to Broadband RGB: 
 - Hα and Oiii (M42 panel only) isolated from RGB continuum
 - Hα applied to R, G for contrast boost of Red / Burnt Orange interstellar dust
 - Hα applied in brighter areas of B to simulate Hß
 - Oiii applied to G, B in M42 area, particularly in brighter core area to maintain Teal color
 - DBE


HRGBO Processing:
 - Rista method TGVD, MMT
 - Masked Stretch, Histogram Stretch
 - Several Unsharp Mask passes
 - Rista method ACDNR
 - Multiple LRGB Combination passes


Final Processing:
 - Star Reduction via Adam Block script, then additional MorphTrans application
 - Additional Masked Stretch application
 - Saturation of Nebula, stars
 - Additional Unsharp Mask passes
 - Numerous Curves/HT color tweaks
 - Isolated blue star halos and ran heavy MMT + SCNR to reduce sensor/grid artifacts
 - Annotation
