M27 final (yeah right )

posting Pixinsight flow, capture data in previous posts

 

work flow Pixinsight

 

batch preprocessing LRGB

registered LRGB

Dynamic crop LRGB

Linear fit

create super lum pixel math mean (LRGB)

LRGB combine with superlum

crop

Histogram stretch, mulitple

(extract LUM for seaprate processing)

curves

MMT chromatic noise

MMT lum

exponential transform smoothing 50 x2

split RGB

 

LUM:

deconvolution (maybe a litle too much)

unsharp mask

curves

 

New LRGB

exponential transform .5/50 smooth

HDR w range mask for just nebula

curves w range mask

color calibration

histogram stretch final

histogram stretch final w range mask

star reduction

 

Photoshop

tweak color channels, saturation etc.
