Guillaume Bigourdan found IC 5058 = B. 438 (= NGC 6965) on 2 Oct 1891 and reobserved on 17 Oct 1897. He reported "this object once appeared rather diffuse and once quite stellar, is distinct from NGC 6963." His position applies to NGC 6965 (misidentified as NGC 6963 in many modern catalogues). Unfortunately the NGC position for 6965 is poor, leading to misidentifications in later catalogues. See NGC 6965.

300/350mm - 13.1" (8/23/84): requires averted vision to confirm, similar to NGC 6961.

13.1" (7/27/84): extremely faint, very small, round. Located 10' N of NGC 6962 within a small equilateral triangle of faint stars.

400/500mm - 17.5" (7/16/88): very faint, small, slightly elongated ~N-S, broad concentration, barely visible continuously with direct vision. Located 10' N of NGC 6962 within a triangle of mag 13-14 stars including a mag 14 star 1.4' E and a mag 13 star 1.3' S. Faintest of six in NGC 6962 group. This galaxy is misidentified in the RNGC, UGC, MCG, CGCG as NGC 6963.

17.5" (8/31/86): very faint (requires averted), small, slightly elongated ~N-S, faint stellar nucleus.

600/800mm - 24" (9/25/19): between faint and fairly faint, very small, round, 20" diameter, faint stellar nucleus. A mag 13 star is 1.4' S and a mag 13.5 star is 1.8' W.
