William Herschel discovered NGC 7562 = H II-467 = h2224 on 25 Oct 1785 (sweep 464) and recorded "pB, pL, irr figure." John Herschel made the single observation "B; S; R; psbM; 15"." While observing NGC 7562 on 16 Sep 1852, George Johnstone Stoney, LdR's assistant, recorded "Involves a very small star to north-following. Another nebula [NGC 7557] 6' preceding and 1' north of it."

400/500mm - 17.5" (8/27/87): fairly bright, moderately large, slightly elongated ~E-W, bright core, stellar nucleus.

17.5" (11/1/86): fairly bright, fairly small, strong bright core, fainter halo slightly elongated ~E-W. Forms a pair with NGC 7557 4.7' WNW. NGC 7591 lies 35' ESE and NGC 7564 36' N.

600/800mm - 24" (1/1/16): fairly bright, fairly large, oval 3:2 ~E-W, ~1.2'x0.8'. Sharply concentrated with a very bright core that increases to the center. The much fainter halo gradually fades out at the periphery. A mag 13.8 star is 1.8' E. NGC 7557 lies 4.6' WNW and NGC 7562A is 2.3' SSE. Two extremely faint "stars" [mag 16.3 or fainter] were glimpsed close to the position of NGC 7562A and one of these may have been the core of the galaxy as it occasionally seemed non-stellar and possibly elongated N-S.
