Description

I started this project in November, and now that Monoceros is near meridian during "prime time" I finally shot the lacking frames. Unfortunately the temperature (-18 celsius) was too much for my laptop that I use for polar alignment, guiding and imaging. I had to shoot the second session without proper alignment using Magic Lantern's intervalometer, which is why I used shorter exposures.

The RGB frames were processed separately and combined with Ha by using Ha as the L-channel.
