View larger image

Messier 67 is a fairly bright open cluster of some 200 stars. It is estimated to be about 4 billion years old, making it one of the oldest known open clusters. Messier 67 is not as well known as the nearby Beehive Cluster (Messier 44), but it is quite an attractive object when viewed with a small telescope at low power.
