Lewis Swift discovered NGC 5758 = Sw. III-83 on 6 Jun 1886 and recorded "eF; pS; R; bright star follows 22 sec." His position is 8 sec of RA west and 1.6' south of UGC 9524. His note of the bright star secures the identification, though the actual separation is 19 sec. Swift missed nearby CGCG 076-043. See Harold Corwin comments.

400/500mm - 17.5" (7/17/01): very faint, very small, round, 20" diameter. A mag 14 star lies 0.9' E. In a group and forms a pair with CGCG 76-043 1.8' ESE. This companion (misidentified as NGC 5758 in the Uranometria 2000.0) appeared very faint, very small, round, 15" diameter. CGCG 76-31 lies 6' W, CGCG 76-53 12' E and NGC 5759 13' S.
