According to "Star Clusters", by Brent Archinal
and Steven Hynes, the size of this open cluster is 7.0 arc
minutes. From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 381 NGC 0381 = Cr 10 = OCL-317 = Lund 38 01 08.3 +61 35 Size 6 17.5" (8/16/93): 40 stars mag 11-15 in loose 6' diameter, stands out best at 100x. The brightest mag 10.8 star is part of a triple along the north side. Fairly uniform in mag 12/13 stars with a scattering of faint stars, fairly even distribution with no rich regions. Not recognizable as a cluster at 220x. 17.5" (11/2/91): about three dozen stars in 6' diameter, fairly faint, roughly a circular group. Consists mostly of mag 12/13 stars. Includes a triple star (10.8/12.5/13 at 8"/~3") and two mag 11 stars on the W side. Several stars are arranged in strings. Relatively few stars in center. A line of mag 10 stars trail off to the N edge of field and the mag 10 star at the end of the string 11' N is a close double star. 8": ~30 stars in a circular group, bright curving string to the north. A mag 8 star is 10' E. - by Steve Gottlieb |
