NGC 2001 (also known as PGC 3518062, 056-SC137, SL 507 and part of LH 64) 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 27, 1826. It's apparent magnitude is 7 by 3.5 arc minutes. and is also known as GC 1204, h 2888, Dunlop 178 according to both cseligman and seds. [2] However, Wolfgang Steinicke lists this as Dunlop 136, not Dunlop 178. [2] [3]
It is around 160 to 165 thousand light year distance of the Large Magellanic Cloud and the loose grouping of stars is about 330 to 335 light years across. NGC 2001 is also listed as part of Lucke-Hodge stellar association 64, along with ANONb4 and e135. [2]
NGC 1755 is an open star cluster in the Large Magellanic Cloud in the Dorado constellation. It is about 120 light years across and due to its size could be a globular cluster. It has a diameter of 2.6′ and an apparent magnitude of 9.9. It was discovered by James Dunlop in 1826.
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 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 2032 is an emission nebula in the Dorado constellation and near the supershell LMC-4 and it consists of NGC 2029, NGC 2035 and NGC 2040. It was first discovered by James Dunlop on 27 September 1826, and John Herschel rerecorded it on 2 November 1834. NGC 2032 is located in the Large Magellanic Cloud.
NGC 2027 is a 12th magnitude open cluster located in the Dorado constellation which is also part of the Large Magellanic Cloud and was discovered by James Dunlop on November 6, 1826. Its apparent diameter is 0.7 arcminutes.
NGC 1873 is an open cluster associated with an emission nebula located in the Dorado constellation within the Large Magellanic Cloud. It was discovered by James Dunlop on September 24, 1826 and rediscovered by John Herschel on January 2, 1837. Its apparent magnitude is 10.4, and its size is 3.50 arc minutes.
NGC 1936 is an emission nebula which is part of the larger LMC-N44 nebula located in the Dorado constellation in the Large Magellanic Cloud. It was discovered by John Herschel in 1834 and added to the Catalogue of Nebulae and Clusters of Stars as NGC 1936. It was later observed by John Dunlop on September 27, 1936 and Williamina Fleming in 1901 and added to the Index Catalogue as IC 2127. Its apparent magnitude is 11.60.
NGC 1929 is an open cluster associated with the emission nebula located within the N44 nebula in the Dorado constellation and part of the Large Magellanic Cloud. It was discovered by James Dunlop on August 3 1826. Its apparent magnitude is 14.0, and its size is 0.8 arc minutes.
NGC 1934 is an emission nebula located in the Dorado constellation and part of the Large Magellanic Cloud. It was discovered by John Herschel on November 23 1834. Its apparent magnitude is 10.50.
NGC 1978 is an elliptical shaped globular cluster or open cluster in the constellation Dorado. It is located within the Large Magellanic Cloud. It was discovered by James Dunlop on November 6, 1826. At an aperture of 50 arcseconds, its apparent V-band magnitude is 10.20, but at this wavelength, it has 0.16 magnitudes of interstellar extinction. It appears 3.9 arcminutes wide. NGC 1978 has a radial velocity of 293.1 ± 0.9 km/s.
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.
