Title: IC 5146 (Cocoon Nebula)
Post by: dpaul on 2018 August 07 16:05:30
Attached image was taken with an Atik Horizon CMOS camera - LRGB filters.
Scope is 30'' F3.5 with Lockwood optics on an 'unguided equatorial platform'.
Each frame was 25 seconds and about 20 frames integrated per filter.

Technically speaking with a 105'' focal length and 3.8 pixel size this is seriously over-sampled. I used 2x2 binning which helps reduce star bloating.
