Berkeley 32 (Biurakan 8) is a trumpler (https://en.wikipedia.org/wiki/Trumpler_classification) class II 2 m open cluster approximately 10,795 light-years away in Monoceros.

Luminance – 28x300s – binned 1x1 – 140 minutes
RGB – 8x180s – 24 minutes each – binned 2x2

212 minutes total exposure – 3 hours 32 minutes

Imaged over six nights in February, March and April, 2024 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.

Very nice image Dan. That's a lot of time to spend on a relatively obscure open cluster. I'm guessing you are attempting to bag all 88 of the Berkeley's?

I am working my way through them. Open clusters make for good targets when the moon is up (and there's nothing to image in narrowband).
