The Great Andromeda Galaxy is one of the farthest objects visible to the naked eye. It can be easily observed even in a light polluted sky. To image the galaxy, you need to take multiple exposures with pretty different exposure times so that you get a correct rendition of both the centre of the galaxy and its outer edges.
