Édouard Stephan discovered NGC 6108 = St XI-45 on 10 Jul 1880. His micrometric position is very accurate.

400/500mm - 17.5" (5/10/86): fairly faint, fairly small, slightly elongated. A mag 15 star is at the WSW edge 34" from center. This is one of the largest galaxies in the NGC 6107 cluster. NGC 6110 lies 4.7' SW and PGC 57737 is 2.0' E.
