Description

My second - only - attempt at M42 in LRGB.  Previously in 2016, I did RGB only with separate filters:  M42 from 2016 - RGB

This time the colour came from the OSC - ASI2600MC camera and added L from the Moravian G4 to the central part of the wide field.

A short exposure as M42 barely clear the roof of my house to the south of the RoR.

Second image acquired with Voyager Advanced.
