NGC 1807 (Collinder 61, Melotte 29 and others) is a trumpler (https://en.wikipedia.org/wiki/Trumpler_classification) class II 2 p open cluster located in Taurus. At least this is what some sources say. Others, including this paper - https://arxiv.org/pdf/astro-ph/0407456v1.pdf - point out that this is probably just an asterism that includes some stars from a NGC 1817, a real, nearby open cluster.

This field also includes some interesting galaxies including PGC 16865 near the center stars and PGC 1508426 and 1508357 near the bottom right.

Luminance – 24x300s – binned 1x1 – 120 minutes
RGB – 8x180s – 24 minutes each – binned 2x2

182 minutes total exposure – 3 hours 2 minutes
