NGC 306 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on October 4, 1836, by John Herschel. [4]
NGC 4402 is a relatively near, edge-on spiral galaxy located around 50 million light-years from Earth. It is in the constellation of Virgo within the Virgo Cluster of galaxies. It can be seen when viewing Markarian's Chain.
NGC 176 is an open cluster around 3.5 million light-years away in the constellation Tucana. It is located within the Small Magellanic Cloud. It was discovered on August 12, 1834, by John Herschel.
NGC 220 is an open cluster located approximately 210,000 light-years from the Sun in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on August 12, 1834 by John Herschel.
NGC 222 is an open cluster located approximately 210,000 light-years from the Sun in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on August 1, 1826 by James Dunlop.
NGC 231 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on August 1, 1826 by James Dunlop.
NGC 241 is an open cluster located in the constellation Tucana. It is located within the Small Magellanic Cloud. It was discovered on April 11, 1834, by John Herschel.
NGC 294 is an open cluster located in the Small Magellanic Cloud in the constellation Tucana. It was discovered on April 11, 1834, by John Herschel, although it was possibly observed on September 5, 1826, by James Dunlop.
NGC 330 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on 1 August 1826 by James Dunlop. It was described by Dreyer as "a globular cluster, very bright, small, a little extended, stars from 13th to 15th magnitude." At an aperture of 31.0 arcseconds, the apparent V-band magnitude is 9.60, but at this wavelength, it also has 0.36 magnitudes of interstellar extinction.
NGC 361 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on September 6, 1826, by James Dunlop. It was described by Dreyer as "very very faint, pretty large, very little extended, very gradually brighter middle." At an aperture of 31.0 arcseconds, its apparent V-band magnitude is 12.24, but at this wavelength, it has 0.40 magnitudes of interstellar extinction.
NGC 5617 is an open cluster in the constellation Centaurus. NGC 5617 forms a binary open cluster with Trumpler 22. It lies one degree west-northwest of Alpha Centauri.
NGC 4815 is an open cluster in the constellation Musca. It was discovered by John Herschel in 1834. It is located approximately 10,000 light years away from Earth.
NGC 4596 is a barred lenticular galaxy located about 55 million light-years away in the constellation Virgo. NGC 4596 was discovered by astronomer William Herschel on March 15, 1784. NGC 4596 is a member of the Virgo Cluster and has an inclination of about 38°.
NGC 720 is an elliptical galaxy located in the constellation Cetus. It is located at a distance of circa 80 million light years from Earth, which, given its apparent dimensions, means that NGC 720 is about 110,000 light years across. It was discovered by William Herschel on October 3, 1785. The galaxy is included in the Herschel 400 Catalogue. It lies about three and a half degrees south and slightly east from zeta Ceti.
NGC 2527 is an open cluster in the constellation Puppis. It was discovered by William Herschel on December 9, 1784. The cluster was also observed by John Herschel on January 7, 1831. He also observed it on February 5, 1837, identifying it as a different object, which was catalogued as NGC 2520. It is a poor cluster and with no central concentration, with Trumpler class III1p.
NGC 779 is a spiral galaxy seen edge-on, located in the constellation Cetus. It is located at a distance of circa 60 million light years from Earth, which, given its apparent dimensions, means that NGC 779 is about 70,000 light years across. It was discovered by William Herschel on September 10, 1785.
NGC 1381 is a lenticular galaxy located in the constellation Fornax. It is located at a distance of about 60 million light years from Earth, which, given its apparent dimensions, means that NGC 1381 is about 55,000 light years across. It is a member of the Fornax Cluster. NGC 1381 appears edge-on and features a thin disk with high surface brightness and a boxy bulge. Both the box-shaped bulge and the kinematics of the central area of the galaxy suggest that NGC 1381 has a bar.
NGC 4380 is an unbarred spiral galaxy located in the constellation of Virgo. Located about 52.2 million light-years away, is a member of the Virgo Cluster, a large galaxy cluster. It was discovered on March 10, 1826, by the astronomer John Herschel.
NGC 910 is an elliptical galaxy in the constellation of Andromeda. NGC 910 was discovered on October 17, 1786 by the German-British astronomer William Herschel. It is the brightest galaxy in the cluster Abell 347.
NGC 1132 is an elliptical galaxy located in the constellation Eridanus. The galaxy was discovered by John Herschel on November 23, 1827. It is located at a distance of about 318 million light-years away from Earth.
