Steve's Notes

===== NGC 2355 18" (3/15/10): fairly rich group with ~70 stars in an 8'-9' diameter group, with the richest portion in the central 4'. On the north side of the central region is a 13" pair of mag 11/12 stars with a mag 13 star 16" S forming an easy triple. The stars are pretty evenly distributed and many are similar magnitudes, though a number appear to be arranged in strings that extend out radially from the center. The brightest member is a mag 10 star on the SE side. The cluster shares the field with mag 8.3 HD 56329 located 7' NNE. 18" (2/23/06): rich cluster at 257x with ~75 stars in an 8' irregular group. Very rich in a 2.5' central "core" with the brightest mag 10 star just SE of this core. The outline is marked by rows of stars giving a triangular outline. Mag 8 HD 56329 lies 7' NE of the cluster. 13.1" (1/18/85): about 50 stars down to mag 14 in a 8'x5' group elongated N-S including a mag 10 star at the SE edge. Rich, fairly compact, a number of stars are arranged in lanes. Located about 7' SW of mag 8.0 SAO 95722.
