Steve's Notes

===== NGC 189 24" (1/4/14): well detached, roundish group of stars at 125x. Using 260x, ~40 stars are resolved in a 5'-6' group. There are several pairs and tight groupings. Many of the stars are in a richer 3' inner group, generally arranged in a ring and including h 1043 = 11.6/12.7 pair at 12" (oriented N-S). A few of the brighter stars, though, form the 6' outline. A distinctive quadrilateral of stars is ~6' NW. 17.5" (11/27/92): 30 stars mag 10-14 in 6' diameter, weakly compressed, no dense areas but appears to have some unresolved background haze. Elongated E-W due to a couple of strings extending to the west. A 6'x5' parallelogram of four mag 9 stars in the field to the south. Not an impressive cluster. 8" (11/13/82): about two dozen stars, moderately large, irregular shape, scattered, haze.
