On the POSS there is an extremely compact companion with dimensions 0.1' x 0.1' just off the east end, and this is probably the "star" noted in the observation.
Lewis Swift discovered NGC 6732 = Sw. V-87 on 16 Oct 1886 and logged "pB; vS; R; F * preceding close north." His RA was 19 seconds too small. Bigourdan measured an accurate RA on 8 Sep 1888. Herbert Howe, observing in 1899-00, reported "this is star-like, and of mag 12.5. The "F * nr" is of mag 11, and precedes 1 second, 0.6' north."
400/500mm - 17.5" (7/20/90): faint, extremely small, round, fairly high surface brightness. A star is possibly involved or a stellar nucleus is offset stellar.
600/800mm - 24" (7/20/17): at 375x; fairly faint, small, irregularly round, 20"-24" diameter, very weak concentration. A mag 12.6 star is 40" NNW of center. At 500x, an extremely faint and small glow (quasi-stellar) often popped momentarily into view just off the east end. This very compact companion [20" E of center] is catalogued as CGCG 280-011 NED2 and LEDA 2413402 at B = 17.1 ± 0.5. UGC calls it a stellar companion at 0.1'x0.1'.
