Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "the general middle of a cluster of loose stars 11..16th mag. It is rich, and fills the whole field."
Shapley and Lindsay ("A Catalogue of Clusters in the Large Magellanic Cloud", Irish Astronomical Journal, Vol. 6, 1963) give a diameter of 80'' and remark "few fairly bright scattered stars."
The RNGC (Sulentic and Tifft 1973) notes that this is a cluster+nebulosity in the LMC.
Date: 2010 February 12/13 (first session).
Location: "Sterland", Sutherland.
Telescope: "Bertha" 12-inch f/4.8 Dobsonian.
Sky conditions: Dark sky, seeing very good, transparency high.
Star chart: MSA 484
The first object in tonight's sweep, which started from delta Dor working southward.
45x, 115x: NGC 2015 is a pretty faint, small (1.2'), round, even nebulous glow, which doesn't grow brighter to the middle. South-east 10' is a small triangle of pB stars; NGC 2015 is slightly larger than its shortest side.
