M 31 (NGC224) Andromeda Galaxy
The Andromeda Galaxy is readily visible from a dark sky location as a fuzzy patch of light covering approximately 3+ degrees or 6 times the width of our moon. Andromeda is approximately 2.5 million light years from Earth and 220,000 light years across. Making it much larger than our own Milky Way galaxy at only 100,000 lights years across. In about 5 billion years both our Milky Way galaxy and Andromeda will collide and begin to coalesce, perhaps evolving into an even larger elliptical type galaxy. This image reveals much detail and numerous globular star clusters and nebulae are visible. Amazing for just a 3.2 diameter refractor, but Thomas Back (TMB) was a primer Telescope Maker and his designs live on.
