Messier 3
Messier 3 (M3 or NGC 5272) is a globular cluster of stars in the northern constellation of Canes Venatici. It was discovered by Charles Messier on May 3, 1764. M3 has an apparent magnitude of 6.2, making it a difficult naked eye target even with dark conditions. Messier 3 is located 31.6 kly above the Galactic plane and roughly 38.8 kly from the center of the Milky Way. It contains 274 known variable stars; by far the highest number found in any globular cluster.

Messier 4
Messier 4 or M4 (also designated NGC 6121) is a globular cluster in the constellation of Scorpius. It was discovered by Philippe Loys de Chéseaux in 1746 and catalogued by Charles Messier in 1764. It was the first globular cluster in which individual stars were resolved. It is one of the easiest globular clusters to be found, being located only 1.3 degrees west of the bright star Antares. The cluster is located at only 7,200 ly from our solar system, being the closest Gb to Earth.

Messier 17 - Omega Nebula
The Omega Nebula also known as Swan Nebula, is an HII region in the constellation Sagittarius. It was discovered by Philippe Cheseaux in 1745 and Chales Messier catalogued it in 1764. It is located in the rich starfields of the Sagittarius area of the Milky Way. It is considered one of the brightest and most massive star-forming regions of our galaxy. Its local geometry is similar to the Orion Nebula except that it is viewed edge-on rather than face-on. The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot young stars. At magnitud 6.0, lies 6,000 light-years from Earth.

Messier 30
Messier 30 (also known as M30 or NGC 7099) is a globular cluster of stars in the southern constellation of Capricornus. M30 is located at a distance of about 27,100 light-years from Earth, and is about 93 light-years across. The cluster is following a retrograde orbit through the inner galactic halo, suggesting that it was acquired from a satellite galaxy rather than forming within the Milky Way. It is currently located at a distance of about 26 klyfor the Sun. The M30 cluster has passed through a dynamic process called core collapse and now has a concentration of mass at its core of about a million times the Sun's mass per cubic parsec. This makes it one of the highest density regions in the Milky Way galaxy.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

Messier 45 - The Pleiades
The Pleiades (also known as the Seven Sisters and Messier 45), are an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth at around 444 ly and is the cluster most obvious to the naked eye in the night sky. The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternative name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing.

Messier 54
Messier 54 (also known as M54 or NGC 6715) is a globular cluster in the constellation Sagittarius. Previously thought to belong to the Milky Way at a distance from Earth of about 50,000 light-years, it was discovered in 1994 that M54 most likely belongs to the Sagittarius Dwarf Elliptical Galaxy. Modern estimates now place M54 at a distance of some 87,000 light-years, translating into a true radius of 150 light-years across. It is one of the denser of the globulars, being of class III (I being densest and XII being the least dense).
