John Herschel discovered NGC 4674 = h3417 on 5 May 1836 and recorded "vF; R: glbM; 30"." An early SN discovery (1907A) was made by Luyten

400/500mm - 18" (4/9/05): faint, fairly small, elongated 2:1 NW-SE, 1.0'x0.5'. At first I only noticed the brighter 0.4' core, but with averted vision the fainter extensions were visible. Located 9' ENE of mag 9 HD 110901 at the edge of the 225x field.
