Messier catalog - the most popular catalog of galaxies and nebulae, especially for beginners. In this catalog the brightest objects of the Deep Space are collected, which are accessible for observation in amateur telescopes.List of Messier objects
Charles Messier (1730-1817) - french astronomer. Since 1751 he worked at the Paris Observatory.
There have been several releases of the Messier catalog , in which objects collected by Charles Messier, astronomer Pierre Meshen and other astronomers have been collected. In total, 110 objects are included in the catalog - galaxies, nebulae and star clusters. Objects are numbered as they are found and entered in the catalog. He did not find all the objects of the Messier catalog himself. Messier studied the records of many of his predecessors, rechecking them. Nevertheless, many objects are open to them.
Astronomer Pierre Meschen, who worked simultaneously with Messier, discovered almost half of the objects from the Messier catalog. His first discovery was the spiral galaxy M63. Messier cross-checked Meshen's messages and put them in his catalog.
The first edition of the Messier catalog was published in 1774 and contained 45 objects.
It is Messier's catalog that we owe the presence of the letter M in the most used names of such objects as:
The globular cluster M13, the Andromeda nebula M31 ...
Messier himself later said that he had previously limited himself to a telescope with a focal length of 60 cm.

Nebulae in catalog Messier
Marathon Messier - a kind of "race" for astronomers, observers. No, with the telescope behind you, there's no need to run anywhere :). The fact is that twice a year, on a new moon in March and in October, such conditions develop, that all objects of the Messier catalog can be seen in one night!
This is the name of the Messier Marathon. Yes, it is rather not about watching the celestial bodies, but about the speeding up of the telescope. Nevertheless, it is difficult not to agree with the fact that even in this case the impressions will be higher than the roof!
Alas, if you read this article at the mentioned time, then ... do not rush to rejoice. In order to perform the Messier marathon, you must be between 10° and 35° north latitude at this time ...
Lives in the north and there is no way to go south with a good telescope? Do not be upset.
The Messier Marathon, albeit in a limited form, can be held in the north.
The main thing is that you now know at what time it's best to do it.
