This image consists of 63 4-minute exposures (stacked using Deep Sky Stacker) taken on Aug. 11, 13 and 14 from my back deck in Abbotsford.
Andromeda is the closest galaxy to the Milky Way, but is still 2.5 million ly distant. Is apparent size is 190' x 60' and completely fills the camera's field of view. The Spitzer space telescope revealed that the galaxy contains one trillion stars, more than the number of stars in the Milky Way galaxy. As can be seen it is a spiral galaxy and is more than 220,000 ly across.
