Best Viewed Objects/Stars

Alpha Aquilae (Altair)

 Among the 20 brightest stars in the sky, at magnitude 0.8, and also one of the closest first magnitude stars to us, only 17 light-years away. It marks the neck of the eagle and forms one corner of the Summer Triangle, completed by Deneb (in Cygnus) and Vega (in Lyra). Altair is flanked by two stars, the 4th-magnitude Beta Aquilae (also known as Alshain) and 3rd-magnitude Gamma Aquilae (or Tarazed).

Eta Aquilae

  A Cepheid variable star, one of the brightest in this important class. Its magnitude varies 3.5 to 4.4 in a cycle lasting 7 days 4 hours, and the changes can be followed with the naked eye or through binoculars. It is a supergiant star, estimated to lie about 1,200 light-years away.
