IC 2602 (and Caldwell 102) (also known as the Theta Carinae Cluster or Southern Pleiades) is an open cluster in the constellation Carina. It was discovered by Abbe Lacaille in 1751 from South Africa. The cluster is at a distance of about 479 light-years away from Earth and can be seen with the naked eye. The Southern Pleiades (IC 2602) has an overall apparent magnitude of 1.9, which is 70% fainter than the Taurean Pleiades, and contains about 60 stars. Theta Carinae, the brightest star within the open cluster, is a third-magnitude star with an apparent magnitude of +2.74. All the other stars within the cluster are of the fifth magnitude and fainter. Like its northern counterpart in Taurus, the Southern Pleiades spans a sizeable area of sky, approximately 50 arc minutes, so it is best viewed with large binoculars or telescope with a wide-angle eyepiece. The cluster is thought to have the same age as the open cluster IC 2391, which has a lithium depletion boundary age of 50 million years old
Very nice, looks much more like a "through telescope" image than many photos. I like it - it's very different. Also it's one of my favourite clusters. Ye,s I have many favourites
