| Notes:* | NGC 366 is the obvious cluster at top near center ... NGC 358
appears to be an Asterism. It is
a small parallelogram of fours stars

just to the West (right) of lower center.
According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of NGC 366 is 4.0 arc minutes. From the NGC / IC Project: Contemporary Visual Observation(s) ...NGC 0358 01 05 10.9 +62 01 14 17.5": consists of just four mag 11-12 stars in a 2'x1' trapezoid at the NGC position. This appears to be clearly just an asterism. 10' SE is also a scattered group in two detached sections elongated E-W with about a dozen mag 12-13.5 stars in each group. - by Steve Gottlieb NGC 0366 = OCL-286 = Lund 37 = Cr 9 01 06 26 +62 13.7 Size 3 17.5": 10 stars mag 12-14 in a small 3' group. Consists of two mag 12-13 stars both of which form very close doubles and a tight trio of mag 13-14 stars on the east side. The rest are faint stars and the cluster is set over unresolved haze. Not impressive but stands out clearly in field. - by Steve Gottlieb |
