Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "The north following nucleus of the complex group of Plate III fig 4, from drawing." Herschel's sketch shows a complex object with four condensations or nuclei, involved in nebulosity. The four objects in this grouping are NGC 2078, 2079, 2083 and NGC 2084.

Henize (Catalogues of Hydrogen Alpha Emission Stars and Nebulae in the Magellanic Clouds, Astrophysical Journal Supplement 2, 1956, p315) this is his nebula LH N 120-159D. He describes it as measuring 2.2' x 1.6', slightly elongated with a smooth edge and showing considerably structural detail.
Shapley and Lindsay ("A Catalogue of Clusters in the Large Magellanic Cloud", Irish Astronomical Journal, Vol. 6, 1963) group NGC 2078, 2083 and NGC 2084 together, giving the dimensions as 3.4' x 2.3'. They remark "scattered bright stars in dense nebulosity."
The RNGC (Sulentic and Tifft 1973) notes that this is a cluster+nebulosity in the LMC.
