Gamma Equulei

 An optical double star, divisible with binoculars. It consist of a star of magnitude 4.7 with a very wide companion, 6 Equulei, of magnitude 6.1.

1 Equulei

 A multiple star. A small telescope shows it as a double with components of magnitudes 5.2 and 7.4. The brighter star is, in fact, a binary with an orbital period of 100 years, but the stars are too close together to be separated with a small aperture.
