Guillaume Bigourdan found IC 4493 = Big. 422 on 12 Apr 1898 and wrote, "rather diffuse nebula, roundish, 35" diameter, granular central region, which stands out quite well". He was searching for H. III-48 (NGC 5747), which has a poor position, and assumed his redisovery was a new object. UGC, CGCG and MCG label this galaxy IC 4493 instead of NGC 5747.

400/500mm - 17.5" (6/20/01): fairly faint, small, round, 40" diameter, weak concentration. A mag 14 star lies 0.9' WNW of center while a brighter mag 12.5 star follows by 3.5'.
