Andrew Common discovered NGC 3723 in 1880 with his 36-inch reflector. His position is just 8 sec of RA following and 1.5' north of MCG -02-30-002 (relatively accurate compared to his generally poor positons).

400/500mm - 18" (3/19/04): fairly faint, small round, 25" diameter, weak concentration to a very small brighter nucleus. In a group (USGC S171 at z = .021) of mostly faint galaxies with several uncertain designations (NGC 3721, NGC 3722, NGC 3724) ~35' NE, as well as NGC 3732 (z = .006), which is 26' ENE.
