Description

https://www.astrobin.com/tq08o0/Reflection Nebula + Dust => awesome!

For reasons unknown I hadn't really looked at many Iris images so I wasn't really aware of just how incredible this nebula is! It's got a lot going on and is quite interesting to dig in to.

Processing:

Lum:
dynamic crop
deconvolution
MLT noise reduction
histogram transformation

Each R, G B:
dynamic crop
DBE
MLT noise reduction

RGB
channel combination
MLT noise reduction (chroma noise)
PCC
histogram transformation
LRGB Combination to add in lum
curves for contrast
SCNR to remove some green cast remaining
LHE (2 scales)
more curves
TGV Denoise
Star De-emphasis script
Dark structure enhance script
Adv Sharpening script
crop to final dimensions
Fixed core of central star in photoshop
