NGC 2074
NGC 2074 is a magnitude ~8 emission nebula in the Tarantula Nebula located in the constellation Dorado. It was discovered on 3 August 1826 by James Dunlop
and around 1835 by John Herschel. It is described as being "pretty bright, pretty large, much extended, 5 stars involved".
Discovery
Some of the objects catalogued by Herschel before 1847 do not have a discovery date listed, and NGC 2074 is one of them. Though its inclusion in the catalog of objects observed in the Large Magellanic Cloud which involves observations carried out between 2 November 1836 and 26 March 1837 shows it must not have been discovered later than that.The observation of NGC 2074 by Dunlop was not identified as this object until recently.
