NGC 6684A lies 30' NE. It was observed on 14 Oct 2015 at 303x with the 3RF 30" near Crookwell. At 303x it appeared very large, low surface brightness glow, irregularly round, ~2' in diameter. Exhibits a very weak central brightening and there was no defined edge to the halo. A pair of mag 13-14 stars is at the southwest edge. Located 30' NE of NGC 6684 and 28' NE of mag 5.7 Theta Pavonis. Nestled in a group of stars, including a mag 9.7 star 2.7' NW, a mag 8.5 star 7.7' SE and a number of mag 13-14 stars.

John Herschel discovered NGC 6684 = h3757 on 8 Jun 1836 and recorded "vB; R; first vg, then psmbM; 90"; a * 6-7m, 7' sp." The RNGC misclassifies this galaxy as a globular cluster.

400/500mm - 18" (7/9/02 - Magellan Observatory, Australia): at 171x this galaxy appeared fairly bright and large, slightly elongated SW-NE, 2.0'x1.6'. Sharply concentrated with a strikingly bright core and a large, slightly oval halo. The core brightens evenly to a stellar nucleus with direct vision. A mag 11 star is off the south side, 2.5' from center. Located 6' SSE of mag 5.7 Theta Pavonis! Member of the NGC 6744 group.
