28cm f/10 SCT Nexstar 11

Small, dim, rich, a barely resolved patch less than 5' across, rich winter galactic star field

Captain William Henry Smyth
Nov 29, 1837    No. 6 The Crescent, Bedford, England (map)
150mm f/17.6 refractor by Tully 1827

A compressed cluster, on the calf of Pollux's right leg, one-third of the distance from Pollux to Rigel, on a line carried from the former star between the second and third "bullions" of Orion's belt to the latter: discovered by ♅. in 1783, and forming No. 415 of his son's Catalogue. It is a faint angular-shaped group of extremely small stars say 12 to 16 magnitudes—which only under the most favourable circumstances can I discern with satisfaction. The region around is immensely rich, and not at all wanting in double stars. Differentiated with γ Gemiriorum for a mean place; and when best seen, it is something like the hasty sketch herewith given.
