Steve's Notes

===== NGC 6273 17.5" (6/3/00): bright, moderately large globular, unusual appearance with an extended halo ~6'x4.5' (elongated N-S) and a bright 3.5' core. The cluster breaks up into several dozen stars at 220x and at 500x at least 50 stars are resolved over the entire face of the globular. There are a couple of strings of stars on the SE side of the halo with a dark lane between the strings. The brightest star is on the northeast side. 13" (7/27/84): bright, elongated N-S, very mottled, brighter core. The outer edges barely resolves into one or two dozen stars at 220x. 13.1" (7/17/82): a number of faint stars just resolve at 280x, particularly around the south edge. 8": lively, two or three very faint stars are resolved at the north edge.
