William Herschel discovered NGC 3274 = H II-358 = h720 on 11 Apr 1785 (sweep 396) and noted "F, pL". His position is a good match with UGC 5721. John Herschel made 4 observations and noted the double star HJ 484 to the southeast.

400/500mm - 17.5" (4/25/92): fairly faint, fairly small, elongated 3:2 E-W, brighter core appears slightly offset. Forms the east vertex of an obtuse isosceles triangle with two mag 12 stars 2' NNW and 2' SW. A double star mag 11.5/13.5 at 13" lies 4' ESE.
