Open Cluster in Canis Major
This is a nice compact cluster of more than 100 stars that shows well in telescopes of all sizes. Many of the most prominent stars in this cluster appear similar in brightness. The cluster was discovered by Caroline Herschel, sister of William, in 1783, the first of her many discoveries of deep-sky objects. It is worth a look on a dark winter night.
