Comet 67P Churyumov-Gerasimenko as it appeared on the night of November 2-3, 2021 in a good return near Earth, after its previous return in 2014-2015 when it was visited by the European Space Agency's Rosetta probe and Philae lander. The comet was faint — about 10th magnitude at this time, but did show a small tail on the photo and a typical cyan glow to its coma. The comet was in Gemini at this time. This is a Jupiter-family comet with a period of 6.45 years.

This is stack of 4 x 4-minute exposures at ISO 1600 with the Canon Ra on the SharpStar 94mm EDPH refractor at f/4.5 and through an Optolong L-Pro filter.
