From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 6755 NGC 6755 = Cr 397 = Lund 878 = OCL-96 19 07 49 +04 16.0 V = 7.5; Size 15 17.5" (8/8/91): at 140x this is a bright group of 80 stars mag 10-14 in a 10' diameter. The stars are arranged in two groups separated by a fairly wide, obvious dark rift oriented SW-NE. The SE star group is larger and richer (about 50 stars) and contains several stars in two rich subgroups. A mag 10 star is at the W edge of the N group. 8": large, scattered, two parts are resolved into rich clumps. - by Steve Gottlieb |
