Max Wolf discovered IC 4015 = W. V-136 and IC 4015, the two components of NGC 4893, on a Heidelberg plate taken 21 Mar 1903. He reported both as "D neb, eF, S, iF, N."

400/500mm - 16" LX200 (4/14/07): faint, very small, round, 15"-20" diameter. A mag 13 star lies less than 1' E. This is a contact double system (IC 4015 + 4016 with a separation of 0.35'), though the components were not resolved. Located 11' SW of NGC 4914 and 82' SE of Cor Caroli (Alpha CVn).

600/800mm - 24" (6/4/16): the two close components (IC 4015 and IC 4016) of NGC 4893 were resolved at 322x. The brighter northern component (IC 4015) of NGC 4893 appeared faint to fairly faint, small, round, 15"-18" diameter. The southern member IC 4016) is faint, extremely small, round, 6" diameter. The centers of the two galaxies are separated by just 19". A mag 13.5 star is 44" E and a mag 15.0 star is just under 1' SSW.
