William Herschel discovered NGC 7794 = H III-466 = h2288 on 23 Nov 1785 (sweep 477) and logged "vF, S, R, lbM." JH made the single observation "eF; irreg fig; pL; 40"." Heinrich d'Arrest measured two micrometric positions and noted the mag 14 star that precedes by 1.9 seconds and a separation of 40".

400/500mm - 17.5" (10/5/91): fairly faint, fairly small, irregularly round, weak concentration. A mag 14 star is just off the SW edge 50" from center.
