Description
NGC 2360 is an open cluster in Canis Major, about 3,700 light-years away. It is a rich, well-concentrated cluster containing about 80 stars within 13 arcminutes, with an age of roughly 2.2 billion years.

A fine cluster in a 4-inch telescope at medium power. The background Milky Way star field adds to the view. Many of the cluster stars are similar in brightness, giving it an even, grainy appearance. Best in winter evenings.
History
Discovered by Caroline Herschel on February 26, 1783. It is one of the notable discoveries by William Herschel's sister, a pioneering astronomer in her own right.
Fun Facts
Caroline Herschel discovered this cluster using a small refractor while conducting her own independent sky surveys. She discovered 8 comets and several nebulae and clusters during her career.
