What is the Messier Catalogue and who was Charles Messier?

The Messier Catalogue is a list of diffuse (fuzzy) objects discovered by French astronomer Charles Messier. Charles Messier was born June 26, 1730, and he devoted much of his life to the search for comets, which generally first appear as diffuse objects.

The telescopes of those days could not provide Messier with the detail that even some of today's most modest telescopes afford amateur astronomers and casual observers. (That being said, he no doubt had far brighter skies to work with since light pollution and smog were not an issue for him.)

As he came across these objects, he would catalog them so that he could go back to these objects later to verify if they were in fact comets or some other object. If the object had moved across the stellar background, than it was most likely a comet. If the object had remained stationary within the stellar background, it was, Messier believed, a nebula or a tight cluster of stars. It turns out that many of these objects are in fact other galaxies. Alas, it was not till the 20th century that the existence of other galaxies would become acknowledged. Charles Messier died at the age of 87 on April 12, 1817.

The Messier Catalog presents some of the nights most beautiful sites in a telescope. They also provide a great means by which to learn the sky. Many of these objects, with a bit of perseverance, are easy to find. Some on the other hand are very difficult objects to find.

Below is a list of Messier objects sorted by Messier number. For your convenience, we have posted the list in a Microsoft Excel 97 (XLS) format. Using the attached list, you can sort on any column you wish. A good example of the usefulness of this file is that you can sort on location. This will sort the list into constellations. As you are learning your way around the sky, it is handy to know what objects happen to be in the constellation you are looking at.
