William Herschel discovered NGC 7332 = H II-233 = h2173, along with NGC 7339, on 19 Sep 1784 (sweep 278) and recorded "pB, E, easily resolvable. I can distinguish one or two stars." On 20 Oct 1784 (sweep 302) he reported "B, lE, the direction nearly in the parallel [N-S]." John Herschel's first observation (sweep 166) reads, "B; S; mE in pos = 163° by microm; vsmbM to a * 11m."

200/250mm - 8" (7/24/82): fairly bright, small bright nucleus, edge-on NNW-SSE. Forms a pair with NGC 7339 5' E.

400/500mm - 17.5" (9/2/89): bright, fairly large, edge-on 4:1 NNW-SSE, well-defined very bright core, stellar nucleus. A mag 11 star is 2.4' SSE of center, collinear with the major axis. Forms a striking pair of edge-on systems with NGC 7339 5.2' E!
