Édouard Stephan discovered NGC 6311 = St VII-11 on 30 Jun 1876. His position is very accurate.

400/500mm - 17.5" (8/1/89): faint, small, irregularly round, weak concentration. Forms a pair with CGCG 225-056 4.8' SW, which appeared extremely faint and small, round, substellar nucleus, very small halo.
