The Summer Triangle
Exoerimenting with some digital astro-photos, I took this 5 minute exposure of the Milky Way centered on the bright stars Vega. top left, Deneb, lower left and Altair, center right. The stars form what is sometimes called The Summer Triangle. Images like this one, which last more than a few seconds, require a mount known as an Equatorial Mount, that allows tracking of the motion of the stars in the sky. Canon 20D - 5 minutes, 20mm @ f/2.8, ISO 400
