Heinrich d'Arrest discovered NGC 7464 = m 514 on 27 Aug 1864 with the 11-inch refractor at Copenhagen while examining NGC 7463 and 7465. NGC 7464 is labeled Roman numeral III in his sketch. Albert Marth independently discovered this galaxy just two months later on 23 Oct 1864 with the 48-inch on Malta ("vF, eS, near NGC 7463]") as well as Hermann Vogel with the 8.5-inch refractor in Leipzig on 10 Aug 1869.

300/350mm - 13.1" (9/22/84): appears as an extremely small "knot" attached at the southeast end of NGC 7463.

13.1" (9/3/83): extremely faint, very small, round, near visual threshold.

400/500mm - 17.5" (9/14/85): faint, very small, slightly elongated WSW-ENE, even surface brightness. Located just 42" SE of the center of NGC 7463 with NGC 7465 1.8' ESE. Located 2.5' NE of mag 8.5 SAO 108339. Member of the NGC 7448 group.

900/1200mm - 48" (10/26/16): at 610x; moderately bright, fairly small, slightly elongated, ~24"x20", broad concentration with no well defined core or nucleus but fairly high surface brightness. Smallest and faintest in an excellent trio with NGC 7463 40" NW and NGC 7465 1.8' ESE.
