What You Should See:

This is a cluster that deserves to be far better known. It is under-observed because of its proximity to its illustrious neighbours, the Pleiades and the Hyades. This big, somewhat sparse, grouping of stars is much better in binoculars than it is in a telescope, where it does not always appear to be an obvious cluster.
