Description

Process same as Messier 76.

The processing was done in PI as follow :
For each H, O channels :
- Images Calibration (Dark and Flat)
- Cosmetic Correction
- Image Registration
- Image Integration
- Mure Denoise
Then :
- Create HO image using pixelmath H in red channel, O in blue channel, H+O in green
- Color balance on nebula
- Deconvolution masked with 2.2 pixel psf
- Delinearisation using MaskedStretch
- Mix image with 50% of HDR compressed image
- SCNR (G min 0.70)
- Color Balance Stars Only using a star mask
- Color Saturation masked (and desaturate bkg)
- Background extraction
- TGV denoise (image as local support)

Final image adjustments performed in Iphoto on Imac :
- levels adjustments
- deflip
