Ormond Stone discovered NGC 5766 = LM 1-212 on 8 Jul 1885 with the 26" refractor at Leander McCormick Observatory. He reported "mag 14.5; 0.3' dia; R; glbMN." His rough position (nearest min of RA) is 1 min of RA west and 1' N of ESO 580-050. Herbert Howe measured an accurate position (repeated in the IC 2 Notes) with the 20-inch refractor at the Chamberlin Observation at the turn of the century.

400/500mm - 17.5" (6/20/01): fairly faint, fairly small, slightly elongated NW-SE, 1.0'x0.8'. Very weak even concentration (not noticeable initially) but no core or nucleus. Forms the southern vertex of a thin isosceles triangle with two mag 12-13 stars 2.3' N and a similar distance NE.
