Édouard Stephan discovered NGC 6332 = St VII-15 on 11 Jul 1876. His declination is slightly off, but Emmanuel Esmiol corrected the position in his 1916 re-reduction ("Réduction des Observations de Nébuleuses Découvertes par M. Stephan").

400/500mm - 17.5" (8/1/89): very faint, fairly small, elongated SW-NE, even surface brightness. NGC 6329 lies 8.7' WNW. Fourth of five in a group.

600/800mm - 24" (9/5/18): at 225x; moderately bright, fairly large, elongated nearly 3:1 SW-NE, ~1.2'x0.4', bright elongated core, moderate surface brightness. A mag 12.4 star is 2.1' NE of center, while two 14th mag stars lie 1.3' NW and 1.7' WNW. Member of a group (WBL 635) with NGC 6329 9' WNW.

PGC 214598, situated 3.5' ESE, appeared very faint [V = 15.5], round, 10" diameter (core region). A mag 14.8 star is close off the NW side [25" from center].
