Alphonse Borrelly discovered NGC 2268 = T I-19 around 1871 with a 7.2-inch comet-seeker at the Marseille Observatory. He noted "pretty faint, extended, elliptic, no bright point" and his micrometric position (MNRAS, 32, 248) matches UGC 3653. Wilhem Tempel independently discovered the galaxy in 1877. The RNGC RA is 8.0 tmin too far east.

400/500mm - 17.5" (8/27/87): fairly bright, fairly large, elongated SW-NE, bright core, faint stellar nucleus. A mag 14 star is at the SW edge 1.1' from center.

17.5" (2/22/87): moderately bright, moderately large, elongated 2:1 SW-NE, faint halo gradually increases to a large brighter core, small bright nucleus, faint stellar nucleus.
