At an apparent magnitude of 4.4, the Andromeda Galaxy is notable for being one of the brightest Messier objects,[10] making it easily visible to the naked eye even when viewed from areas with moderate light pollution. Although it appears more than six times as wide as the full moon when photographed through a larger telescope, only the brighter central region is visible with the naked eye.
