Dan Crowson
 

Berkeley 55 is a trumpler (https://en.wikipedia.org/wiki/Trumpler_classification) class III 2 p open cluster approximately 5545 light-years away in Cygnus.

 

Luminance – 24x300s – binned 1x1 – 120 minutes

RGB – 8x180s – 24 minutes each – binned 2x2

 

182 minutes total exposure – 3 hours 2 minutes

 

Imaged September 9th, 10th and 12th, 2021 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

Dan, 

I really like how the color of the cluster comes through so distinctly compared to the general star field.
