Frank Muller discovered NGC 7104 = LM 2-462, along with NGC 7103, in 1886 with the 26" refractor at the Leander McCormick Observatory. He noted "mag 14.3; 0.2' diam; iR; gbMN; 2nd of 2 [with NGC 7103]." His position is 1.0 minute of RA too far east. Ormond Stone measured an accurate micrometric position the following year (repeated in the IC 1 Notes). ESO/Uppsala misidentifies ESO 531-017 as NGC 7104.

400/500mm - 17.5" (10/13/90): faint, very small, round, small bright core, stellar nucleus. Second brightest of four in ACO S963 with NGC 7103 4.0' SW, IC 1393 2.7' ENE and IC 5122 4.2' WNW.
