Truman Safford discovered NGC 4308 = Sf 107 on 11 Jun 1868 with the 18.5" refractor at the Dearborn Observatory. The discovery was not published until 1887, too late to be credited in the NGC. Wilhelm Tempel independently discovered the galaxy on 17 Feb 1882, recorded it in list V-16, and was credited with the discovery in the main NGC listing. Tempel's and Safford's position matches UGC 7426.

400/500mm - 17.5" (4/25/98): faint, small, round, 30" diameter, very weak concentration. Located 13' NW of NGC 4314. Observation hampered by poor transparency.
