Heinrich d'Arrest discovered NGC 4728 on 3 Mar 1867 with the 11-inch refractor at Copenhagen. His position, measured on two consecutive nights, is accurate. This is the brightest of three with (R)NGC 4728A = UGC 7992 at 2.2' ESE and (R)NGC 4728C at 3.6' NNE.

400/500mm - 17.5" (3/20/93): faint, small, round, even surface brightness. A mag 11 star is 3.3' SSW. This outlying member of AGC 1656 forms a trio with NGC 4728A = UGC 7992 2' ESE and NGC 4728B 3.5' NNE. NGC 4745 lies 13' E. Located 18' SE of 30 Comae Berenices (V = 5.8) and 17' SW of 31 Comae (V = 4.9). The CGCG magnitude =15.6z is too faint.
