  Messier object - Wikipedia, the free encyclopedia
The Messier objects are a set of astronomical objects catalogued by Charles Messier in his catalogue of Nebulae and Star Clusters first published in 1774.
The original motivation behind the catalogue was that Messier was a comet hunter, and was frustrated by objects which resembled but were not comets.
Because all of the Messier objects are visible with binoculars or small telescopes (under favorable conditions), they are popular viewing objects for amateur astronomers.

 Astronomy Online - Messier Objects
Messier's goal was not to study these fuzzy objects on Messier's list, but Astronomers today still refer to the Messier Objects as some of the more prominent deep space objects.
There are 110 of these objects, and they have since been absorbed into a newer catalog - called the New General Catalog (or NGC), however observational purists still refer to the "M" in Messier when viewing these objects through a telescope.
The Messier Object catalog is not specific to one type of object but has a variety of galaxies, star clusters and nebulae.

 Messier Club Introduction   (Site not responding. Last check: 2007-10-21)
Messier did not discover all the objects in his catalog and he never made any such claim.
Since the purpose of the Messier Club is to familiarize the observer with the nature and location of the objects in the sky, the use of an automated telescope which finds the objects without effort on the part of the observer is not acceptable.
Also "Messier marathon" sessions where all the objects are found in one occasion is to be discouraged if the beginning observer depends on other experienced observers to find the object to be observed.

Although these objects looked like comets, Messier knew that since they did not move with respect to the background stars they could not be the undiscovered comets he was searching for.
Objects on Messier's list are still referred to by their "Messier number".
For example the Andromeda Galaxy, the 31st object on the list, is known as M31.

 Robert Bruce Thompson's Winter Messier Objects Presentation - Introduction
Messier wasted a lot of time looking at objects he thought might be comets, only to find out later they were star clusters, nebulae, or other objects—stuff that didn’t move.
Messier continued observing for many years after adding his last object, but the short answer is that he could no longer compete so he stopped trying.
Size is rather arbitrary, because the visible extent of many objects depends on the size of your telescope, the darkness of your skies, the quality of your night vision, and your level of observing experience.

 M1 The Crab Nebula
Messier was a comet hunter, and using less sophisticated and crude telescopes of the time, found that objects like the Crab Nebula were confusing and could be mistaken for comets.
The idea behind the list was a catalogue of nebula and star clusters which would aid observers who might otherwise confuse the objects with comets, and thereby waste time observing a deep sky object that was not a comet.
The Messier List, originally intended as a list of things to "avoid" in the sky by comet hunters in the 1700's, is now regarded as a list of the finest deep sky objects that an amateur astronomer can observe with a telescope or binoculars.

Messier Objects are well known "objects to avoid" as compiled by Charles Messier (to avoid confusion with comets).
It is the "modern" Messier Catalog for amateur astronomers that seek deep sky delights that are both challenging and rewarding; however there are no Messier listings in the Caldwell Catalog.

It was one of the first major milestones in the history of the discovery of Deep Sky objects, as it was the first more comprehensive and more reliable list: Only four objects were initially missing because of data reduction errors, which could be figured out later though.
The study of these objects by astronomers has, and continues to, lead to important, incredible discoveries such as the life cycles of stars, the reality of galaxies as separate 'island universes,' and the possible age of the universe.
All of the Messier objects can be observed with modest amateur telescopes and are all within the scope of the DERA 6” Zeiss refractor.

 The Herschel 400 List -- Brighter Than You Think
So part of Jay's object in writing the post must have been to disabuse people of that notion, part of it probably was to suggest some methods to get the most of what limited aperture one might have, and yet more of it was likely to simply get people to challenge themselves with their scopes.
The second-faintest Herschel 400 object, according to the Astronomical League's data, is NGC 6369, with a visual magnitude of 14.0 given.
The third- and fourth-faintest objects, according to the Astronomical League's data, are the planetary nebulae NGC 1501 and NGC 7008, both with magnitudes given as 13.5, but with recent visual magnitudes of 11.5 and 10.7 respectively.

 Zoom Astronomy Glossary: M
During the late 18th century (1759-1781), the French astronomer Charles Messier made a list of 103 fuzzy objects in space in order not to mistake star clusters, galaxies, and nebulae for comets (for which he was searching).
Lower numbers represent brighter objects than higher numbers; very bright star are 1st magnitude, less bright stars are 2nd magnitude, etc. The magnitude scale is logarithmic; a difference in magnitude of 5 is a 100-fold increase in brightness (the difference in each successive magnitude is a factor of about 2.512 times).
The Messier list has been added to and now consisted of 35 galaxies, 30 open clusters, 29 globular clusters, 4 planetary nebulae, 7 diffuse nebulae, and two unconfirmed objects (which were mistaken for nebulae by Messier).
