According to "Star Clusters", by Brent Archinal
and Steven Hynes, the size of this open cluster is 15 arc
minutes. From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 6866 NGC 6866 = Cr 412 = Mel 229 = Lund 917 20 03 55 +44 09.5 V = 7.6; Size 7 17.5": about 100 stars in a 20'x10' region are visible at 100x. Appears rich and very appealing. The main string is very elongated roughly E-W and contains a brighter intersecting subgroup 8'x2' NW-SE of about 45 stars with a close triple star on the NW end consisting of a mag 10 star and two very faint companions. Two mag 10-10.5 stars are at the SE end of this string. The western end of the main string curves north into a nice semi-circle. - by Steve Gottlieb |
