Description

===Capture===
133 Ha at 300s, 200 gain 50 offset
 48 O3 at 900s, 200 gain 50 offset
230 S2 at 300s, 200 gain 50 offset
50 R at 15s, 200 gain 50 offset
50 G at 15s, 200 gain 50 offset
50 B at 15s, 200 gain 50 offset
Bortle 7 suburban zone

Drizzle 2x

===SHO===
LinearFit S2 and O3 to Ha
SHO in PixelMath
AutoColor script
Stretch with HistogramTransformation
StarXTerminator
Curves with color masks on starless image

===RGB Stars===
RGBcombination of RGB filters
Autocolor script
Register to LRGB
Masked Stretch
HistrogramTransformation
Apply luminance of stars extracted by StarXTerminator
Add RGB stars with PixelMath to SHO
MMT Noise Reduction

===Luminance processing===
Create Ha+S2 luminance
  Create S2Mask: Stretch S2, range mask to focus on interesting regions
  Mask Ha with S2Mask (protect non-S2 regions)
  Pixinsight (Ha+S2)/2

Stretch Histogram

Add contrast with LocalHistogramEqualization
(Mask off background, 200 kernel radius, 1.5 contrast limit, 1.0 amount)

===LRGB===
Linearfit Lum to Luminance of SHO
Apply Lum to RGB with LRGBCombination
Contrast curve
Lum mask, then slight MMT noise reduction (Amount 0.10)
50% downsize Resample
