This website is part of a long-term effort to provide a good online atlas of the heavens. The Messier list serves as an, admittedly imperfect, best deepsky objects list for viewers in the northern hemisphere. Each entry includes the object's name, location on a sky map (right ascension and declination), type (with images), constellation, magnitude (brightness), and size. Messier objects include open clusters, globular clusters, galaxies, and nebulae. There is a Caldwell List with the same data about objects not on the Messier list. The Jack Bennett Catalog contains Messier objects for the Southern Hemisphere. Other lists provide similar information for additional objects that have been found.
