Francis Leavenworth discovered NGC 5743 = LM 1-209, along with NGC 5734, on 3 Jun 1885 with the 26-inch refractor at the Leander McCormick Observatory and recorded "F; S; vE; smbMN." His position (nearest min of RA) is just 2' north of ESO 580-017, though the RA of nearby NGC 5734 is 1 minute too small. Herbert Howe's corrected position (repeated in the IC 2 Notes) is accurate.

400/500mm - 18" (5/29/05): moderately bright, moderately large, elongated nearly 3:1 E-W, 1.2'x0.4', broad concentration. Larger and brighter of a close pair with NGC 5743 2.6' N.
