The Milky Way and the stars of the Summer Triangle (Vega, Deneb, and Altair) over the Mount Wilson Observatory near Los Angeles. In the foreground is one of the CHARA Array telescopes; an interferometer made of six 1 meter telescopes with a maximum separation length of 330 m which make it the World's highest angular resolution telescope at near-infrared wavelengths. On the background is the 60 inch telescope which received its "First light" on December 8, 1908 when it was the world's largest operational telescope. Mt Wilson is one of the most productive and successful observatories in astronomical history.
