Édouard Stephan discovered NGC 6692 = St XIII-91 on 11 Aug 1883 and recorded "vF, vS, irr elongated E-W, sev vf * inv." His micrometric position is very accurate.
400/500mm - 17.5" (7/5/86): fairly faint, small, round, weak concentration, slightly elongated ~E-W. A bright double star (∑2372 = 6.4/8.1 at 25") is 8' SE.
