NGC 1874, NGC 1876, and NGC 1877 are three emission nebulae in a large complex star-forming region in the LMC. ESO did not provide separate positions for them, so those adopted here come from GSC or from offsets to GSC stars. JH's positions are excellent for the first two, adequate for the third -- but that comes from a sketch drawn on 17 Jan 1838, not from one of the sweeps, so I'd expect lesser accuracy for it.
John Herschel recorded it as "the south preceding of two, forming a binuclear nebula at the southern extremeity of an arc-formed cluster of stars." The other object is NGC 1876. Also in this grouping are NGC 1877 and NGC 1880.
Henize (Catalogues of Hydrogen Alpha Emission Stars and Nebulae in the Magellanic Clouds, Astrophysical Journal Supplement 2, 1956, p315) describes it as measuring 65 x 73 arcseconds, round with a smooth boundary and only slight structural detail.
Shapley and Lindsay ("A Catalogue of Clusters in the Large Magellanic Cloud", Irish Astronomical Journal, Vol. 6, 1963) group NGC 1874, 1876 and NGC 1877 together as a 2.4' x 2.4' group of "bright scattered stars in nebulosity."
The RNGC (Sulentic and Tifft 1973) notes that this is a cluster+nebulosity in the LMC.
