Large loose cluster of stars, chiefly about 10 mg., closely np 19, a 6 mg. yellow star, attended by a fine group. 19 seems larger than 6 mg. to my unaided eye.

150mm f/17.6 refractor by Tully 1827

A compressed cluster, in the space under the haunches of Monoceros, where a line from Arneb drawn through Sirius, and extended rather more than as far again to the east, will find it as the eastern point of a triangle, equilateral with Sirius and Procyon. It consists of a large and loose, but rich, group of small stars pretty equally strewed over the field, with a close double star in the middle, and a bright yellow one of the 6th magnitude to the sf. It was registered by ♅. in January, 1785.
