Francis Leavenworth discovered NGC 5734 = LM 1-206, along with NGC 5743, on 3 Jun 1885 with the 26-inch refractor at the Leander McCormick Observatory and recorded "vF; S; lE; glbM." There is nothing at his rough position (nearest min of RA), but 1 min of RA east is ESO 580-016. Herbert Howe's corrected position (repeated in the IC 2 Notes) is accurate and he noted that NGC 5734 and 5743 have the same RA, not 1 minute apart, per Leavenworth. According to Wolfgang Steinicke, this is the first galaxy discovered at the LM Observatory.

400/500mm - 18" (5/29/05): fairly faint, fairly small, elongated 2:1 SW-NE, 0.7'x0.4'. A mag 13 is just off the NE tip, 30" from center, and detracts from viewing. Forms a close pair with NGC 5743 2.6' S.
