William Herschel discovered NGC 7156 = H III-452 = h2135 on 8 Oct 1785 (sweep 461) and recorded "vF, pL, R, r." CH's reduced position is 2' northwest of UGC 11843. JH made three observations, logging it as "F; R: pL; 40"; vglbM" on sweep 295, and measured an accurate position.

400/500mm - 17.5" (8/1/86): fairly faint, fairly small, round, weak concentration, irregular surface brightness, appears mottled.
