Description

Good old M42. I did 5 minutes per primary color and about 1.5 hours worth of Ha
I did simple pixel math and added the Ha channel to red and after that some cropping and clean up.

Title: Slightly filtered M42

Description: I saw that there were some artifacts in the image. Likely caused by the low number of RGB frames. I dither during guiding, but with this low number of frames you will not get the dead pixels out
Using a gaussian filter makes it look a little less ugly
