William Herschel discovered NGC 1682 = H II-527, along with NGC 1684 = II-528, on 1 Feb 1786 (sweep 518), and logged "Two, the 1st vF, vS." His position is 40 tsec too far east, the same offset applying to II-528. JH missed this galaxy, only recording NGC 1684 = h334. The NGC position (from d'Arrest) is accurate.

400/500mm - 17.5" (12/23/89): fairly faint, small, slightly elongated, bright core, stellar nucleus. Located 4.0' N of mag 8.0 SAO 131557. In a group with NGC 1684 3.0' E and NGC 1683 5' N.
