The Orion Nebula, January 21, 2020
This is my best yet of the Orion Nebula
See some of my Past Pictures of Orion

This is a continuation of an experiment using filters on a One-Shot-Color camera (Altair Hypercam 394c ProTEC). It is a blend of 30 minutes each of no filter, Hydrogen Alpha (Ha) 12nm and Oxygen 3 (O-III narrowband). I used the red from the Ha and the blue from the O-III filter. Most of the processing was done in Photoshop CC 2020
