Messier objects.
Color of Messier objects.
This group contains between 8 and 24 galaxies,including three Messier objects.

Location===Because Messier compiled his catalog from a northern latitude, not all of the Messier objects are visible from the southern hemisphere.

A Messier marathon is an attempt,usually organized by amateur astronomers, to find as many Messier objects as possible during one night.
Toggle whether Messier objects are rendered as images in the sky map.
Other times of year===Less complete Messier marathons can be undertaken at other times of the year,with the actual percentage of Messier objects seen depending upon season and location.
Today, most Messier objects are easy to find with a small telescope.
Season===At low northern latitudes, particularly around latitude 25° north,it is possible to observe all Messier objects in one night during a window of a few weeks from mid-March to early April.
He investigated the missing Messier Objects, concluding that M91 was probably a comet and that M102 was probably a duplication of M101.
The constellation's most obvious deep-sky object is the naked-eye Andromeda Galaxy(M31, also called the Great Galaxy of Andromeda),the closest spiral galaxy to the Milky Way and one of the brightest Messier objects.
It displays the highest blue shift of all Messier objects, as it is approaching the Milky Way at 244 km/s.
There are organized activities associated with DSOs such as the Messier marathon which occurs at a specific time each year andinvolve observers trying to spot all 110 Messier objects in one night.
Moore compiled a list of 109 objects to match the commonly accepted number of Messier objects(he excluded M110), and the list was published in Sky& Telescope in December 1995.

The Perseus Spiral arm contains a number of Messier objects: The Crab Nebula(M1) Open Cluster M36 Open Cluster M37 Open Cluster M38 Open Cluster M52 Open Cluster M103.
Charles Messier(French:; 26 June 1730- 12 April 1817) was a French astronomer most notable for publishing an astronomical catalogue consisting of 110 nebulae andstar clusters, which came to be known as the Messier objects.
Moore compiled a list of 109 objects- to match the commonly accepted number of Messier objects(110 minus the duplicate 102 acknowledged by Méchain)- and the list was published in Sky& Telescope in December 1995.
The number of Messier objects visible in any one night varies depending on a few factors, including the location of the observer, the duration of daylight and nighttime, and the season the positions of the Messier objects relative to the Sun varies with the season.
The command Slew orders the telescope to move to a particular target, and once the telescope reaches its target,the telescope keeps tracking that target at a sidereal rate( i. e. the rate at which stars move across the sky). This works well for stars, Messier objects, and about everything outside our solar system. But solar system objects travel differently across the sky and so the telescope must Track the objects as they move.
Set the faint magnitude limits for NGC/ Messier objects when zoomed in and zoomed out. These magnitude limits do not affect IC objects, as the magnitudes for many IC objects are undefined.
The Messier objects are a set of astronomical objects catalogued by the French astronomer Charles Messier in his"Catalogue des Nébuleuses et des Amas d'Étoiles"("Catalogue of Nebulae and Star Clusters"), originally published in 1771, with the last addition(based on Messier's observations) made in 1966.
Charles Messier then compiled a catalog of 103"nebulae"(now called Messier objects, which included what are now known to be galaxies) by 1781; his interest was detecting comets, and these were objects that might be mistaken for them.
When and where a marathon is possible==The number of Messier objects visible in any one night varies depending on a few factors, including the location of the observer, the duration of daylight/nighttime, and the season the positions of the Messier objects relative to the sun varies with the season.
