C88 소개
설명
NGC 5823 is an open cluster in Circinus, about 3,400 light-years away. Also known as the Hidden Treasure Cluster, it contains about 80 stars spread across 10 arcminutes with an age of roughly 700 million years.
관측 팁
A moderately rich cluster requiring a 4-inch telescope to resolve. Located in the southern Milky Way, the rich star field can make the cluster boundaries difficult to define. Medium magnification works best. Best in winter and spring from southern locations.
역사
Discovered by James Dunlop in 1826 from Australia. It lies in the obscure constellation Circinus near the galactic plane.
재미있는 사실
NGC 5823 is old enough that its more massive stars have evolved away from the main sequence, and several red giants are visible among the cluster members.
