Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F, pS, lE, easily resolvable, some of the stars visible."
Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pB, irr R, 25 arcseconds, involves a double star (13m + 14m)." On a second occassion he called it "F, E, bM, resolvable, binuclear, pos 62.4 degrees. Rather an equivocal object, whether nebulous or a group, but I incline to regard it as a nebula."
Together with NGC 7285 listed as No. 93 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "long faint plume bifurcates from arm, eastern component in other arm."
NGC 7284/5, Cat.of South.Peculiar Gal.and Ass. Vol 2 (Arp&Madore, 1987) p2.8.
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads E,BM,CONT W/7285.
Steve Coe, using a 17.5" f/4.5, notes: "Faint, small, elongated 1.5 X 1 in PA 90. A double star is involved with this galaxy. At 100X it just appears as a fuzzy double star, going to 165X makes it look like a galaxy with two stellar nuclei that are seperated by one arc minute."
