Description

M42 is tough to process because of the bright core.  I used a 20x60sec subs stacked separately from the 30x300sec exposures.  DSS and Siril was used to process, and the core was combined with the rest of the Nebula in Photoshop.  With a close look, the trapezoid is visible.  I tried to leave the luminosity in place at the expense of some noise.
