Lewis Swift discovered IC 1260 = Sw. IX-80 on 15 May 1890 and logged "eeeF; S; R; forms equilateral triangle with two others; 3rd of 3." Three years earlier he found IC 1258 and IC 1259, so he apparently revisited the group and detected this galaxy.

600/800mm - 24" (7/22/14): faint to fairly faint, very small, round, 12" diameter. Located 2' ESE of IC 1258 and 2.6' SSE of IC 1259 = Arp 310 (close double system!). The entire group forms Arp 311.

24" (8/15/12): faint, very small, round, 12"-15" diameter. Faintest of trio of IC galaxies with IC 1258 and IC 1259 (forming Arp 311) and situated just 1.9' ESE of IC 1258.
