Messier Deep-Sky Objects (M1 - M110)
The Messier catalog contains 110 "famous" deep-sky objects (galaxies, nebulae, and star clusters) that are relatively bright and close to Earth. As such, they are not that difficult to see in northern skies using small beginner (4-inch) telescopes. Astronomy clubs and star parties may host a Messier Marathon where the goal is to find all 110 objects (M1 thru M110) in a single night!
