John Herschel discovered NGC 3308 = h3279 on 24 Mar 1835 and simply noted "F". Less than a week later he added "One of a group; 7 of which were seen and laid down in a careful diagram."

300/350mm - 13.1" (2/18/04 - Costa Rica): moderately bright, fairly small, slightly elongated SSW-NNE, 1.0'x0.8', broad concentration to a brighter core. Furthest NW in the core of AGC 1060 and 11.5' WSW of the mag 5 star in the core.

13.1" (2/23/85): fairly faint, small, round, small weak concentration. First of five in a 20' field in the core of AGC 1060.

600/800mm - 24" (3/28/17): fairly bright, fairly small, slightly elongated, well concentrated with a small, very bright core, ~1.0'x50". Slightly fainter than NGC 3309.
