Best Viewed Objects/Stars
A Cepheid variable star. It is a yellow-white supergiant that ranges between magnitudes 3.9 and 4.8 every 9 days and 2 hours. It lies about 540 light-years away.
A close double star with components of unequal brightness. It consists of a red giant of magnitude 4.4 and an 8th magnitude companion, both about 420 light-years away. With a telescope of small aperture, it may be difficult to pick out the fainter star in the glare around the brighter component.
A globular cluster, just visible to the naked eye and easy to see with binoculars or a small telescope. A telescope with an aperture of 3 in (75 MM) will resolve individual stars. The cluster has an apparent size about half that of the full Moon and lies 14,000 light-years away.
