Orion's Sword - Orion and Running Man Nebulae - 11/09/2021 (Processed Cropped Stack)

Imaged at dark skies site, Youndegin, WA.
Also see uncropped version.

First dark site use of Astronomik L2 UV/IR Cut filter in filter slot for QHY 268C CMOS camera. A disappointing result with asymetric corner focus as well as poor centre focus, and possible collimation error shown by double points on bright star off centre.
