Dorado is a constellation in the Southern Sky. It was named in the late 16th century and is now one of the 88 modern constellations. Its name refers to the mahi-mahi, which is known as dorado ("golden") in Spanish, although it has also been depicted as a swordfish. Dorado contains most of the Large Magellanic Cloud, the remainder being in the constellation Mensa. The South Ecliptic pole also lies within this constellation.
NGC 1783 is a globular cluster within the Dorado constellation and part of the Large Magellanic Cloud, a satellite dwarf galaxy of the Milky Way. At an aperture of 50 arcseconds, its apparent V-band magnitude is 10.39, making it one of the brightest globular clusters in the LMC as viewed from Earth. It was discovered in 1835 by John Herschel. The compiler of the New General Catalogue, John Louis Emil Dreyer, described this cluster as "considerably bright, large, round, very gradually pretty much brighter middle, mottled but not resolved."
NGC 2164 is a 10th-magnitude open cluster in the Dorado constellation. The celestial object was discovered on September 27, 1826, by the Scottish astronomer James Dunlop. Its apparent size is 2.5 arcmin. It is located in the Large Magellanic Cloud.
NGC 1820 is an open cluster in the Dorado constellation. It is located within the Large Magellanic Cloud. It has a magnitude of 9.0 and was discovered by John Herschel on 2 January 1837.
NGC 2197 is an centrally condensed open cluster within the Large Magellanic Cloud, in the Dorado constellation. It is estimated to be 400 million years old.
NGC 1869 is an open cluster in the Dorado constellation. It is located within the Large Magellanic Cloud. It was discovered by James Dunlop on September 24, 1826, using a telescope reflector with a nine-inch aperture. It is a large cluster of rich scattered stars. It is part of a triple association with NGC 1871 and NGC 1873. It has an apparent magnitude of 14.0.
NGC 1858 is a bright, large, irregular open cluster and emission nebula. It is found in the Dorado constellation. It is located in the Large Magellanic Cloud. It was first discovered by James Dunlop on August 3, 1826, and was first recorded as Dunlop 120. John Herschel recorded it on November 2, 1834. However, at the time, he did not associate it with Dunlop 120. Astronomers have now realised that Dunlop 120 and NGC 1858 are the same object.
NGC 2002 is an open cluster located in the Dorado constellation and is part of the Large Magellanic Cloud. It was discovered by James Dunlop on September 24, 1826. Its apparent magnitude is 10.1, and its size is 2.0 arc minutes.
NGC 1987 is an open cluster or a globular cluster located in the Mensa constellation and part of the Large Magellanic Cloud. It was discovered by John Herschel on November 3, 1834. Its apparent magnitude is 12.1, and its size is 1.7 arc minutes. It is thought to be around 600 million years old and has a significant number of red ageing stars.
NGC 1955 is an open cluster associated with an emission nebula located in the Dorado constellation. This nebula is part of the H II region which is part of the Large Magellanic Cloud and was discovered by James Dunlop on August 3, 1826. Its apparent magnitude is 9.0, and its size is 1.8 arc minutes.
NGC 1971 is an open cluster which is in the Dorado constellation and is part of the Large Magellanic Cloud. It was discovered by John Herschel on December 23, 1834. Its apparent size is 11.9 by 0.80 arc minutes.
NGC 1959 is an open cluster located in the Mensa constellation which is part of the Large Magellanic Cloud. It was discovered by John Herschel on December 23, 1834. Its apparent magnitude is 12.2, and its size is 0.50 arc minutes.
N11 is the brightest emission nebula in the north-west part of the Large Magellanic Cloud in the Dorado constellation. The N11 complex is the second largest H II region of that galaxy, the largest being the Tarantula Nebula. It covers an area approximately 6 arc minutes across. It has an elliptical shape and consists of a large bubble, generally clear interstellar area, surrounded by nine large nebulae. It was named by Karl Henize in 1956.
NGC 1974 is an open cluster associated with an emission nebula which is located in the Dorado constellation which is part of the Large Magellanic Cloud. It was discovered by James Dunlop on November 6, 1826, and later observed by John Herschel on January 2, 1837, subsequently cataloged as NGC 1991. Its apparent magnitude is 9.0 and its size is 1.7 arc minutes.
NGC 1997 is an open cluster located in the Dorado constellation which is part of the Large Magellanic Cloud. It was discovered by John Herschel on November 30, 1834. Its apparent magnitude is 13.43 and its size is 1.80 arc minutes.
NGC 1986 is an open cluster which is located in the Mensa constellation which is part of the Large Magellanic Cloud. It was discovered by James Dunlop on September 27, 1826. It has an apparent magnitude of 11.31 and its size is 2.80 by 2.40 arc minutes.
NGC 1983 is an open cluster associated with an emission nebula which is located in the Dorado constellation and part of the Large Magellanic Cloud. It was discovered by John Herschel on 11 November 1836. It has an apparent magnitude of 9.9 and its size is 1.0 arc minutes.
NGC 1984 is an open cluster associated with an emission nebula, it is located in the constellation Dorado in the Large Magellanic Cloud. It was discovered by John Herschel on 16 December 1835. The apparent magnitude is 9.9 and its size is 1.50 by 1.20 arc minutes.
NGC 643 is an open cluster located on the far outskirts of the Small Magellanic Cloud in the southern constellation of Hydrus, approximately 200,000 light-years from Earth. Due to their close proximity to NGC 643, the open cluster ESO 29-SC44 and the galaxies PGC 6117 and PGC 6256 are also designated NGC 643A, NGC 643B and NGC 643C, respectively. NGC 643 is relatively old. Its brightest stars have an apparent magnitude of 19.
