Alpha is a naked-eye optical double while Beta is a true double. A double star is two stars that are gravitationally attracted, and revolve around each other from a common central point. Optical doubles are two stars that appear to be related but, in fact, have nothing to do with each other and in many cases are hundreds of light years apart. The two components that form the naked eye optical double shine at magnitude 3.6 and 4.2. The brighter star is about 500 light years away from us while the fainter star is only about 100 light years away.
Beta is an easy binocular double.
Component A shines at magnitude 3.1 and component B at 6.0. Moving to the other side of Capricornus, just east of the star Zeta lies an 8th magnitude Globular Cluster, M30. At 30,000 light years this faint object is a challenge to any observer. The most challenging object for binoculars is the Planetary nebula NGC 7293, better known as the Helix Nebula. A huge shell of gas blown off by a dying star, about half the size of the full moon but extremely dim.
