Equipment Details:

Canon 6D Mk2 with Canon 75-300mm EF mount and a homemade combination dew-light pollution shield. I also position a patio umbrella to block an LED street light that would otherwise shine directly into my camera lens.

Post-processing Details:

370 light frames and twelve dark frames taken over two nights (Dec 7th and Nov 13th). Almost all (95%) were 300mm F/5.6, 20 seconds, ISO 1600. Sequator, then GIMP. Sequator at 25% light pollution reduction helps a lot in post processing.

Image Details:

Old reliable M42 and Running Man. Light pollution in my area is increasingly atrocious, but I can still easily find M42 without the need for a GOTO mount. I modified a vintage Celestar 8 mount to hold the camera and lens, track M42 and maintain relatively round stars. Astropheric said both nights would be good for imaging, and they were.
