Description

Experimenting with my Samyang F135 with a planetary camera. Since I don't have a cooled astronomy camera, and my ASI485MC probably produces better images than my unmodified EOS 7D.
I also used a clip-in Optolong L-Pro with a custom made 3D-printed adapter. 
This is the result of 240 images, 30s exposure time by GAIN 100. 20 flat, bias and dark frames processed by Siril and Gimp.

Not sure why the brighter stars Alnitak and Alnilam have a halo. Maybe stopping down further (from 2.8 tot 4.0) will help?
