Engelhardt discovered one IC object during his extensive observations of nebulae with the 12" f/12.6 Grubb refractor at his private observatory in Dresden; see: Observationes Astronomique, Deuxieme Partie, Dresden 1890, p. 218-219. It is IC 1463 in Aquarius, found Aug. 29, 1886. Unfortunately the object is only a pair of stars.
