Notes:* NGC 366 is the obvious cluster at top near center ... NGC 358 appears to be an Asterism. It is a small parallelogram of four stars (image from the CDS) 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.

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.

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.
