August 11, 2017 – Double Stars

Albireo

Albireo in the constellation Cygnus (The Swan)

Evening Highlights:
  • Albireo: Appearing as a single star in the constellation Cygnus, through a telescope it resolves to a beautiful double system of gold and blue.
  • Alcor and Mizar: Found in the handle of the Big Dipper/Ursa Major, it’s one of the few naked eye double stars.  Even more interesting – it’s actually a sextuple system!
  • Epsilon Lyrae: Found in Lyra, if looking through binoculars you’ll see two widely separated stars.  Look through a telescope, and you’ll find that each ‘star’ is actually a double!
  • Saturn: With its rings tilted to over 27 degrees this year, it will be tonight’s focus for planetary viewing.  Jupiter and Mars will also be visible.
