NGC 7315 is a lenticular galaxy in the constellation of Pegasus. It was discovered on 11 September 1872 by Édouard Stephan. It was described as "very faint, extremely small, round, brighter middle" by John Louis Emil Dreyer, the compiler of the New General Catalogue.
NGC 7499 is an unbarred lenticular galaxy within the constellation Pisces. NGC 7499 is its New General Catalogue designation. It was discovered on September 2, 1864 by the astronomer Albert Marth.
NGC 352 is a barred spiral galaxy in the constellation Cetus. It was discovered on September 20, 1784 by William Herschel. It was described as "pretty faint, small, irregularly extended" by John Louis Emil Dreyer, the compiler of the New General Catalogue; he also noted an "8th magnitude star 97 seconds of time to east" relative to the galaxy.
