SH2-155 (C9) Cave Nebula
« on: Sep 20, 2021, 11:42:10 »
I've redone the last 3 steps of processing, no Dark Structure Enhance or SCNR (green removal). I also reduced the saturation to a more 'natural' level (at least for me). The dust element is now more prominent.

Might have overdone the Dark Structure Enhance script in Pixinsight, but it adds drama :)
107x240s, Gain 120, Offset 4, Temp -5C

"Might have overdone the Dark Structure Enhance script" :o  It needs to be used with subtlety  8)

If the dark areas go too black then it's probably overdone.
