Lewis Swift discovered NGC 7132 = Sw. II-89 on 18 Oct 1884 and recorded "vF; pL; lE; bet 2 stars; 5 stars west? in form of a pyramid. My memory locates the stars east of the nebula." His position is 22 seconds of RA too large but the description pins down the identification (the stars are west). Rudolph Spitaler measured an accurate position on 6 Nov 1891 with the 27" refractor in Vienna (corrected in IC 1 Notes) as well as Bigourdan on 3 Oct 1888.

400/500mm - 17.5" (7/16/88): very faint, very small, elongated E-W, small bright core. An extremely faint star is possibly involved. A mag 10.9 star is located 1.1' W.
