According to "Star Clusters", by Brent Archinal
and Steven Hynes, the size of this open cluster is 6.0 arc
minutes. From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 7261 NGC 7261 = Cr 450 = Lund 1013 = OCL-237 22 20.2 +58 05 V = 8.4; Size 6 18" (8/17/04): at 225x, ~30 stars are resolved in an 7'x3.5' group, elongated N- S. A couple of scattered groups of stars are to the south, but are apparently detached. 7 stars on the south side form the outline of a perfect rectangle with the eastern vertex the brightest star in the cluster (mag 9.5 SAO 34332). There are no stars within the interior of this rectangle. The richest group of stars is just north of the rectangle. 17.5" (10/5/91): about 30 stars in a 7'x3' region elongated N-S. Set over a background of some unresolved haze on the N side of cluster. Includes six brighter stars with a mag 9 star on the SE side. Fairly rich in faint stars on the N side although not rich in other sections. - by Steve GottliebHistorical Research Notes / Correction for NGC 7261 NGC 7261. JH's cluster is probably the scattered group of pretty bright stars, stretching nearly north-south across an area 15' by 10', about 20 seconds preceding his position for the bright star on its following edge. There is a smaller core (7' by 5') of generally fainter stars about five arcminutes north-northeast of the center of the larger group. Is this perhaps a background cluster? - Dr. Harold G.
