Steve's Notes

===== NGC 6535 24" (7/30/16): at 500x; moderately bright and large, roundish, ~3' diameter, fairly weak concentration with a slightly brighter core. A mag 13 star is on the southwest side of the halo, two mag 13.5 stars on the west side and another near the northwest edge. A half-dozen stars additional stars are resolved in the halo with a few additional around the edges of the halo. A number more scintillate in and out of view, emerging for brief moments in better seeing, ~20-25 total seen in the halo. The core region includes another half-dozen stars with one standing out more prominently. 18" (8/23/03): at 435x, appears fairly faint, ~3' diameter with an irregular outline, and just a weak concentration. A trio of mag 13-13.5 stars is easily resolved on the west edge and the middle star has two close, mag 14.5 and 15.5 companions. With careful viewing about a dozen extremely faint stars sparkle over the central glow, often popping in out of averted vision. At 538x, the cluster barely breaks up into a swarm of extremely faint stars in steady moments. 17.5" (8/10/91): moderately bright, roughly circular, 3' diameter. Three mag 13 stars and a mag 14 star are almost on a line oriented N-S on the west edge. Very mottled and granular appearance with an irregular outline. Can just steadily resolve a few very faint stars and another half a dozen extremely faint stars pop in and out of view over the core. Located within a rich star field.
