The Hyades is the large cluster adjacent to α Tauri (Aldebaran), which is not itself a member.

What You Should See:

This cluster, the second closest to us at a distance of about 150 light years, overflows a 5° field of view. For this reason, it is far better in binoculars than it is in a telescope. The brighter stars form the 'V'-shape with which we are familiar as the head of the Bull. The Hyades lies at the approximate centre of a larger grouping of stars, the Taurus Moving Cluster, some members of which are over 45° from the Hyades. Several tens of stars are revealed by 10×50 binoculars. Also worth a look is the cluster NGC 1647 which is just to the NE.
