Definitions Astro "Messier Objects"
Ok I looked in two dictionary and could not find "Messier Objects".
Would one of you kind astronomers give a layman's definition to me. Hi: The Messier Objects are those deep sky objects (nebulae, galaxies, star clusters) discovered or at least catalogued by Charles Messier (1730-1817). The original "purpose" of Messier's list, which, depending on who you listen to, contains between about 100 and 110 objects, was to aid comet hunters. Messier, a comet hunter himself, wanted to list fuzzy objects that could be mistaken for comets by those seeking them. Since many of the DSOs Messier put in his catalogue could not have been mistaken for comets, even with the telescopes of his age, it seems that he went beyond his original idea to make the list of "interesting" objects we still enjoy today.

The SEDS site listed as a link at the bottom of the page is a good one too,
unfortunately it appears their site has been hit by hackers, check it out when they resolve their problem... |

They are the object that are not neater. g
Actually, they are mostly the objects cataloged by the French Comet-Seeker Messier to list stationary objects which might, under some conditions, resemble a comet. These include almost every type of deep-sky object, as well as some products of "averted imagination". Clear, Dark, Steady Skies! (And considerate neighbors!!!) |

There is a nice description at http://www.synapticsystems.com/sky/messier.html. The page also includes a list of the Messier Objects and a link to a biography of Charles Messier.

Very simply, a Messier object is any one of the 110 (109, if you exclude M102 as a duplicate observation of M101) objects catalogued by Charles Messier during the late 18th century. They are designated, M1 through M110. Most also have designations in Dreyer's New General Catalog (NGC).

He created a list of fuzzy objects that were definitely not comets, for the purposes of ruling them out in future observations. A few of the objects on the list weren't actually added by him, but it has since been used as a reference for some of the best objects for observing in the sky. -- - Mike Remove 'spambegone.net' and reverse to send e-mail. |
