John Herschel discovered NGC 6770 = h3784, along with NGC 6769 and 6771 on 11 Aug 1836 and logged "eF; 15". The 2nd of 2." His RA is 1.0 minute too large and he probably reversed the declinations of this galaxy and NGC 6767. DeLisle Stewart provided an accurate RA (given in the IC 2 Notes), based on plates at Harvard's Arequipa Station in Peru.

400/500mm - 18" (7/9/02 - Magellan Observatory, Australia): this close companion to NGC 6769 is just 1.9' following and appears fairly faint, fairly small, round, 1.0' diameter with a small brighter core. On the DSS a straight spiral arm points directly towards the southeast end of NGC 6769, apparently as a result of the interaction. NGC 6771 lies 2.9' S.

600/800mm - 25" (10/17/17 - OzSky): at 244x; NGC 6770 is the disrupted, eastern member of an interacting pair with NGC 6769 (1.8' between centers). It appeared moderately bright or fairly bright, roundish, sharply concentrated with a bright elongated core or bar oriented NW-SE. In a rich star field with a mag 12.2 star is just off the west side [0.9' W of center] and a mag 13 star is at the east edge of the halo. NGC 6771 is 3' S and IC 4845 lies 14.5' NE.
