John Herschel discovered NGC 366 = h83 on 27 Oct 1829 and reported a "small cl 2' in diam. Place that of the double star h 1070." His position, though, is 2' S of the double star.

400/500mm - 17.5" (11/6/93): 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.

600/800mm - 24" (1/4/14): small, rich group with 30 stars resolved in a 3' region at 260x, with several small knots of stars. On the south side is the multiple star STI 177 A/B/C = 12/12.9/13 at 3.8" and 10". Just 48" NE, is the 12" mag 12/13 D and E components with a fainter component at 7" and another close pair or triple is ~30" E. On the N end of the group is DAM 304 = 12/14 pair at 9". A string of mag 14-15 stars oriented SW-NE is on the west side of the main grouping.
