NGC 6242
22" (6/28/06 - Hawaii): bright, rich group of ~100 stars in a 12' region with most of the stars to the north of a mag 7.3 orange luminary. The group is elongated N-S and highlighted by a N-S string of 8 or 9 brighter mag 9-10 stars on the west side of the cluster.
11" (8/8/04 - Haleakala Crater): 80-100 stars in a 12' cluster including a mag 7.3 orange star (HD 152524) on the SE side. There is an elongated group (N-S) of ten mag 10 stars to the NW of the bright star. These brighter stars are set over a rich carpet of mag 13-14 stars. A couple of curved chains of stars forms the southern boundary of the cluster.
17.5" (7/16/93): ~100 stars in a 10' region at 220x, rich in faint stars. Includes red mag 7.3 SAO 101654 in the SE corner of cluster and 8 brighter mag 10-11 stars. Includes several curving arcs of stars with a few dozen mag 13 stars and a rich background carpet of mag 14.5-15.5 stars.
8" (6/27/81): two dozen stars mag 8-11, fairly rich, compact, nice at low power. Faint stars are visible with averted vision.
