Description

My 2017/2018 attempt on M42. The 2016 data (2 hr) were taken under very poor seeing. They are only included to enhance S/N in darker area where there are no sharp features.

Rev.B is a version of less contrast stretching.

Rev.C is a 2x zoom-in of the Trapezium region composed from only the short exposures.

Rev.D is a reprocessing in Aug 2021, based on the same set of data. The new processing improves the highlight, sharpness, noise, and the overall color balance.
