Mag: B=?, V=?
Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "cluster of very faint stars and nebula. See 'First Approximation Towards a Catalogue of Objects in the Magellanic Clouds...'."
Henize (Catalogues of Hydrogen Alpha Emission Stars and Nebulae in the Magellanic Clouds, Astrophysical Journal Supplement 2, 1956, p315) notes that his nebula LH N 120-158 "contains NGC 2081." His nebula measures 12.4' x 12.7', is considerably elongated with an extremely irregular outline and showing very marked structural detail.
The RNGC (Sulentic and Tifft 1973) notes that this is a cluster+nebulosity in the LMC.
