William Herschel discovered NGC 5690 = H II-582 = h1846 on 30 Apr 1786 (sweep 558) and recorded "F, mE, about 2' long, 1/4' broad, r. The stars and nebulosity together make a pretty appearance." CH's reduced position is 2' south of UGC 9416." JH made three observations and noted "a vF ray 60" l; follows a *7m dist 5'."

300/350mm - 13.1" (5/26/84): faint, very elongated NNW-SSE. A very faint star is at the SSE end. Located 3.3' ENE of mag 6.6 SAO 120569, which interferes with viewing!
