Édouard Stephan discovered NGC 7724 = St V-13 = T I-55 = T IV-14 on 23 Sep 1873 and recorded "eF, moderate extent; irregular." His micrometric position is accurate. Wilhelm Tempel independently found the galaxy again on 26 Nov 1877 and measured an accurate micrometric position in 1880. He was surprised WH, JH, d'Arrest and LdR missed this galaxy, although they all viewed nearby NGC 7727.

300/350mm - 13.1" (10/10/86): faint, moderately large, slightly elongated SW-NE, diffuse but edges well defined, even surface brightness. A mag 10 star (SAO 165813) lies 5.6' SSE. Located 12' WNW of NGC 7727.
