Francis Leavenworth discovered NGC 3722 = LM 2-442, along with NGC 3724, in 1886 and noted "mag 15.0, round, 0.2', sbMN, 1st of 2 [with N3724]." There is nothing at his position, but this number is generally equated with MCG -01-30-005, which lies 1.8 min of RA east (good match in dec). The error in RA is fairly common in the LM discoveries, though there is no galaxy southeast to match NGC 3724 (a companion is northeast).

Corwin proposes PGC 170153 as NGC 3722. This galaxy is a closer match in RA (less than 1 min of RA west) and agrees in declination. Also, NGC 3734 would match IC 2910 in relative offset. See NGC 3734.

400/500mm - 17.5" (4/5/97): extremely faint, very small, round, 15" diameter. First of close trio with MCG -01-30-007 = NGC 3724 (uncertain ID) 1.8' NE and MCG -01-30-008 4.0' NE. Also nearby is MCG -01-30-003 (possibly NGC 3730) 6.4' NNW and a two anonymous galaxies 9' and 10' NNE. Located 10' NNE of NGC 3732. The galaxies in this group have uncertain NGC designations due to poor positions by Leavenworth.

600/800mm - 24" (3/9/13): faint to fairly faint, small, round, 18" diameter, fairly low even surface brightness. Brightest of four in a 4' string, including extremely faint MCG -01-30-006 = PGC 35753 just 0.7' NNE. PGC 35753 appeared extremely faint to very faint, round, just 6" diameter! Member of a large group (USGC S171) at z = .021.
