Orion Nebula (M42/NGC 1976) and Running Man Nebula (Sh2-279)
I extracted the starless Red channel from the L-eXtreme integration and combined with the RGB image from the UV-IR Blocking filter to enhance the reds.
The RGB image is with the Astronomik L2 UV-IR Blocking Filter under Bortle 4 skies of Joshua Tree National Park. I arrived late at 10 PM, so I only kept 10 subs at 180 secs before the background became too bright due to the light pollution near the horizon.
The extracted red Ha channel is with the Optolong L-eXtreme Filter under Bortle 8 skies at home.
I attempted an HDR composite by imaging at 10, 30, and 180 seconds to retain the detail and color near the Orion Trapezium Cluster and pull out the faint nebulosity.
