Description

7hrs 30mins total exposure selected (58% of total acquired data as I believe my collimation is slightly out and star eccentricity wasn’t great)

Rough process: Integrate, starless DBE, generate dynamic PSF, deconvolution, replace stars, EZ denoise, PCC, stretch

Extra denoise with ACDNR, various extra stretches and curves with masks to bring out galaxy and star contrast and kill background chrominance.

SCNR and final manual stretches used on individual colour channels to neutralise background and try to align final colours to the PCC’d frame.
