NGC 307 is a lenticular galaxy in the constellation Cetus. It was discovered on September 6, 1831 by John Herschel. [2]
NGC 300 (also known as Caldwell 70) is a spiral galaxy in the constellation Sculptor. It is one of the closest galaxies to the Local Group, and probably lies between the latter and the Sculptor Group. It is the brightest of the five main spirals in the direction of the Sculptor Group. It is inclined at an angle of 42° when viewed from Earth and shares many characteristics of the Triangulum Galaxy. It is 94,000 light-years in diameter, somewhat smaller than the Milky Way, and has an estimated mass of (2.9 ± 0.2) × 1010M☉.
NGC 4725 is an intermediate barred spiral galaxy with a prominent ring structure, located in the northern constellation of Coma Berenices near the north galactic pole. It was discovered by German-born astronomer William Herschel on April 6, 1785. The galaxy lies at a distance of approximately 40 megalight-years from the Milky Way.
NGC 7600 is a galaxy about 160 million light-years from Earth, located in the constellation Aquarius. It is classified as a lenticular galaxy, or, more formally, an S0 galaxy.
NGC 613 is a barred spiral galaxy located 67 million light years away in the southern constellation of Sculptor. This galaxy was discovered in 1798 by German-English astronomer William Herschel, then re-discovered and catalogued by Scottish astronomer James Dunlop. It was first photographed in 1912, which revealed the spiral form of the nebula. During the twentieth century, radio telescope observations showed that a linear feature in the nucleus was a relatively strong source of radio emission.
NGC 1746 is an asterism in the constellation Taurus that was described in 1863 by Heinrich Louis d'Arrest and as a result was recorded in the New General Catalogue (NGC). Previously, the object was classified as an open cluster; however, it was shown through more recent observations that it is a random formation of stars in Earth's sky, an asterism. NGC 1746 has an apparent magnitude of 6.1 and an apparent size of about 40'.
NGC 178 is a Magellanic spiral galaxy in the constellation of Cetus. The compiler of the New General Catalogue, John Louis Emil Dreyer noted that NGC 178 was "faint, small, much extended 0°, brighter middle". It was discovered on November 3, 1885 by Ormond Stone.
NGC 6905, also known as the Blue Flash Nebula, is a planetary nebula in the constellation Delphinus. It was discovered by William Herschel in 1784. The central star is 14.0 mag. The distance of the nebula, as with most planetary nebulae, is not well determined and estimates range between 1.7 and 2.6 kpc.

NGC 237 is a spiral galaxy located in the constellation Cetus. It was discovered on September 27, 1867 by Truman Safford.
NGC 260 is a spiral galaxy located in the constellation Andromeda. It was discovered on August 27, 1865 by Heinrich d'Arrest.
NGC 274 is a lenticular galaxy in the constellation Cetus. It is a pair of galaxies, the other being NGC 275, which it is currently interacting with. It was discovered on September 10, 1785 by William Herschel. It is roughly 120 million light-years away.
NGC 298 is a spiral galaxy in the constellation Cetus. It was discovered on September 27, 1864 by Albert Marth. NGC 298 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 14.7, NGC 298 is visible with the help of a telescope having an aperture of 20 inches or more.
NGC 304 is a lenticular galaxy in the constellation Andromeda. It was discovered on October 23, 1878, by Édouard Stephan.
NGC 308 is a star located in the constellation Cetus. It is only 55" away from NGC 307. It was recorded on December 31, 1866, by Robert Ball.
NGC 315 is an elliptical galaxy in the constellation Pisces. It was discovered on September 11, 1784 by William Herschel.
NGC 327 is a spiral galaxy in the constellation Cetus. Also known as "The Jamie Smith Star" (ISD0534203) and was discovered on September 27, 1864 by Albert Marth. It is described by Dreyer as "faint, small, extended." It is nearby galaxies NGC 329, NGC 325 and NGC 321.
NGC 347 is a spiral galaxy in the constellation Cetus. It was discovered on September 27, 1864, by Albert Marth. It was described by Dreyer as "very faint, very small."
NGC 375 is an elliptical galaxy located in the constellation Pisces. It was discovered on September 12, 1784 by William Herschel. It was described by Dreyer as "pretty faint, small, round, brighter middle." Along with galaxies NGC 379, NGC 380, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 375 forms a galaxy cluster called Arp 331.
NGC 7184 is a barred spiral galaxy located in the constellation Aquarius. It is located at a distance of circa 100 million light years from Earth, which, given its apparent dimensions, means that NGC 7184 is about 175,000 light years across. It was discovered by William Herschel on October 28, 1783.
NGC 539 is a barred spiral galaxy in the constellation of Cetus south. It is estimated to be 429 million light years from the Milky Way and has a diameter of approximately 200,000 ly.
