William Herschel discovered NGC 4092 = H III-382, along with NGC 4095 and 4098, on 26 Apr 1785 (sweep 402) and recorded "Three, the time is that of the last [NGC 4098], which is vF and S. The other two which are south-preceding are much fainter and smaller." His single position is 11 seconds of time east and 2.5' north of[NGC 4098 = UGC 7093.

Heinrich d'Arrest measured an accurate position for UGC 7087 on 4 nights and questioned if it was one of WH's three objects. Dreyer credited d'Arrest with the discovery of NGC 4092 and Dreyer states in his 1912 Scientific Papers that WH probably saw NGC 4093. But Harold Corwin argues that NGC 4092 is brighter and most likely seen by WH, despite being further south.

400/500mm - 17.5" (5/14/88): faint, very small, round, weak concentration. A mag 11.5 star is close NW 0.9' from center. This galaxy is the third of six in the field with NGC 4093 2.6' NNE in the NGC 4065 cluster.
