William Herschel discovered NGC 3475 = H III-332 = h800 on 10 Apr 1785 (sweep 394) and noted "vF, about 1' north aof a small star." Caroline's reduced position falls nearly 4' south of UGC 6058. On 28 Mar 1832 (sweep 407), John Herschel wrote, "vF; R; gbM; 2' s of a * 12m." His position was fairly accurate.

400/500mm - 17.5" (4/9/99): easily picked up at 100x while scanning the field. Fairly faint, fairly small, elongated 3:2 ~WSW-ENE. Well concentrated with a bright, round core and an ill-defined diffuse halo at least 1' along the major axis. A mag 13 star is 1.4' N. A couple of nearby faint companions were not seen but MCG +04-26-023 located 9' N was observed.
