NGC 131 is a spiral galaxy that was discovered on September 25, 1834, by John Herschel. This galaxy belongs in the NGC 134 group of galaxies: NGC 115, NGC 148, NGC 150, PGC 2000, IC 1555, and PGC 2044.
NGC 150 is a barred spiral galaxy in the constellation Sculptor. It is about 70 million light years away from the Solar System, and it has a diameter of about 55,000 light years. It was discovered on 20 November 1886, by Lewis A. Swift. The Type II supernova SN 1990K was detected in NGC 150, and was reported to be similar to SN 1987A.

NGC 334 is a barred spiral galaxy in the constellation Sculptor. It was discovered on September 25, 1834 by John Herschel. It was described by Dreyer as "very faint, small, round, gradually a little brighter middle, 2 stars of 11th magnitude to south."
NGC 365 is a barred spiral galaxy in the constellation Sculptor. It was discovered on November 25, 1834 by John Herschel. It was described by Dreyer as "faint, small, round, gradually a little brighter middle."

NGC 409 is an elliptical galaxy located in the constellation Sculptor. It was discovered on November 29, 1837 by John Herschel. It was described by Dreyer as "extremely faint, small, round, very small (faint) star near."
NGC 415 is a spiral galaxy of type SB(rb)b located in the constellation Sculptor. It was discovered on September 1, 1834 by John Herschel. It was described by Dreyer as "very faint, small, round, gradually a little brighter middle."
NGC 418 is a barred spiral galaxy of type SB(s)c located in the constellation Sculptor. It was discovered on September 28, 1834 by John Herschel. It was described by Dreyer as "faint, pretty large, round, very gradually a little brighter middle, western of 2.", the other being NGC 423.
NGC 423 is a lenticular galaxy of type S0/a? located in the constellation Sculptor. It was discovered on November 14, 1835 by John Herschel. It was described by Dreyer as "extremely faint, small, extended, gradually a little brighter middle, eastern of 2.", the other being NGC 418.
NGC 427 is a spiral galaxy of type (R)SB(r)a: located in the constellation Sculptor. It was discovered on September 25, 1834, by John Herschel.
NGC 438 is an intermediate spiral galaxy of type (R')SAB(s)b: located in the constellation Sculptor. It was discovered on September 1, 1834, by John Herschel. It was described by Dreyer as "pretty faint, small, round, gradually a little brighter middle."
NGC 439 is a lenticular galaxy of type SAB0^-(rs)? located in the constellation Sculptor. It was discovered on September 27, 1834 by John Herschel. It was described by Dreyer as "pretty bright, small, round, gradually brighter middle."
NGC 441 is a lenticular galaxy of type (R')SB(rs)0/a? located in the constellation Sculptor. It was discovered on September 27, 1834, by John Herschel. It was described by Dreyer as "prety faint, small, round, gradually brighter middle."
NGC 461 is an intermediate spiral galaxy of type SAB(s)c located in the constellation Sculptor. It was discovered on September 25, 1834 by John Herschel. It was described by Dreyer as "pretty bright, round, gradually a little brighter middle ."
NGC 972 is a dusty spiral galaxy in the northern constellation of Aries, located at an approximate distance of 49.8 Mly from the Milky Way. It was discovered in 1784 by William Herschel. The galactic features suggest it may have undergone a merger with a gas-rich companion, giving it asymmetrical arms, plus starburst activity in the nucleus and an off-planar nuclear ring. The inner 3.6 kpc of the galaxy is undergoing star formation at the rate of 2.1–2.7 M☉·yr−1, but it lacks a nuclear bulge.
