NGC 2259
18" (3/4/08): at 175x, appears as a 4' rich group of faint stars over haze. At 300x, about two dozen stars in total are resolved, mostly in a 2' circular clump. About 1' N of this dense patch of stars is the brightest mag 11.5 star which has a 13th magnitude companion. This cluster is located 5' E of mag 8.8 HD 47271.
17.5" (2/1/92): fairly faint, small, 3'-4' diameter, rich, irregularly round. Consists of about 15 faint stars mag 13.5-14.5 sparkling over a layer of background haze. A double star mag 12/13 at 7" separation is at the north edge. Mag 8.7 SAO 95930 is 5' W and is surrounded by a less compressed group of 15-20 stars mag 12/13 in a 6' triangular shape. This mag 8.7 star has two faint companions on the south side and another close faint double star is 3' NE.
