Description

The Soul Nebula in Hubble Pallette

PixInsight Processing

--------------------------------

weighted batch processed

dynamic crop to remove stacking artifacts

screen transfer function to find background for extraction

dynamic background extraction

- left default points but adjusted threshold where needed

create masks blur at 3

- cyan

- magenta

- green

mask magenta

curves transformation

- pull down lower limits of red down

- desaturate

mask green

curves transformation (goal is to get greens to yellow gold)

- middle of green down

- middle of red up

- middle of blue down

- rgb brighten

- reapply previous transforms again

- CIE up on high end

mask cyan

curves transformation

- middle of blue up

- middle of green down

- if pink pull red down

- rbg brighten

- CIEB down

- saturation up

- reapply above

- red down

- rgb brighten

- lightness up when oversaturated

- CIEB down

remove masks

curves transformation

- brighten / darken

- increase saturation

- increase CIEC

- almost cartoonish

red mask

- take red down

Noise Reduction

- clone H master

- histogram stretch

- increase contrast

- add as mask to H layer

- multiscale linear transform - noise reduction

- histogram stretch

- apply as inverted mask

back to copy of sho

- convoultion - blur

LRGB combination

- Curves transformations

Local Histogram Equalization

Apply Star Mask

Morphalogical Transformation
