Description

Captured over three consecutive nights - a long time since that happened. 
PI processing steps:
Calibrate, sub frame selection, stack
Stack Ha,R,G,B masters using default settings in ImageIntegration tool to create synthetic L
crop Ha,R,G,B and synthL
ABE on all Masters adjusting settings from default making sure to try and avoid nebulosity 
Linear fit R,G,B
Channel combine R,G,B
ArcSinh stretch RGB, followed by curves for saturation/contrast
HistogramStretch synthL followed by curves and LHE for contrast.
LRGBCombine followed by curves/saturation
HistogramStretch Ha followed by curves for contrast.
NBRGBCombination
Replace HaRGB stars with RGB stars using the a/b channel extraction/combination technique.
Final curves for saturation/contrast.
