Messier 1 (Crab Nebula)
The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The common name comes from William Parsons, who observed the object in 1840 using a 36-inch telescope and produced a drawing that looked somewhat like a crab. The nebula was discovered by English astronomer John Bevis in 1731, and it corresponds with a bright supernova recorded by Chinese astronomers in 1054. The nebula was the first astronomical object identified that corresponds with a historical supernova explosion.

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.

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 53 & NGC 5053
Messier 53 (also known as M53 or NGC 5024) is a globular cluster in the Coma Berenices constellation. M53 is one of the more outlying globular clusters, being about 60,000 light-years (18.4 kpc) LY away from the galactic center, and almost the same distance (about 58,000 light-years (17.9 kpc)) from the Solar system. NGC 5053 is the another globular cluster in the same constellation discovered by German-British astronomer William Herschel on March 14, 1784. As recently as 1995, it was considered the most metal-poor globular cluster in the Milky Way. The chemical abundances of the stars in NGC 5053 are more similar to those in the dwarf galaxy Sagittarius Dwarf Galaxy than to the Milky Way halo. Along with the kinematics of the globular cluster, this suggests that NGC 5053 may have been stripped from the dwarf galaxy.

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). It shines with the luminosity of roughly 850,000 times that of the Sun and has an absolute magnitude of −10.0.

It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars. If we could step out our galaxy and look it from space, the Milky Way will look like NGC 5236; only difference will be that our galaxy doubles the size of NGC 5236. The red spot on the galaxy arm are “stars nurseries”. Telescope: Meade LX850 12" f/8 Camera: SBIG STF-8300C Date: May 2015 Exposure: 36 x 10' = 6 hrs |

Messier 92
Messier 92 (also known as M92, or NGC 6341) is a globular cluster of stars in the northern constellation of Hercules. It was discovered by Johann Elert Bode in 1777, then published in the Jahrbuch during 1779. The cluster was independently rediscovered by Charles Messier on March 18, 1781 and added as the 92nd entry in his catalogue. M92 is at a distance of about 26,700 light-years away from Earth. M92 is one of the brighter globular clusters in the northern hemisphere, but it is often overlooked by amateur astronomers because of its proximity to the even more spectacular Messier 13. It is visible to the naked eye under very good condition Telescope: William Optics GTF-81 f/5.9 Camera: QHY168C Filters: Optolong L-Pro Date: September 2018 Exposure: 32x5' = 2.7 hrs |

Messier 95
Messier 95 (also known as M95 or NGC 3351) is a barred spiral galaxy about 38 million light-years away in the constellation Leo. It was discovered by Pierre Méchain in 1781, and catalogued by Charles Messier four days later. The center of the galaxy contains a ring-shaped circumnuclear star-forming region with a diameter of approximately 2000 ly.

Messier 103
Messier 103 (also known as M103, or NGC 581) is an open cluster where a few thousand stars formed in the constellation Cassiopeia. This open cluster was discovered in 1781 by Charles Messier's friend and collaborator Pierre Méchain. It is one of the most distant open clusters known, with distances of 8,000 to 9,500 light-years from the earth and ranging about 15 light-years apart. There are about 40 member stars within M103, two of which have magnitudes 10.5, and a 10.8 red giant, which is the brightest within the cluster. M103 is about 25 million years old Telescope: William Optics GTF-81 f/5.0 Camera: QHY-168C Filter: Optolong L-Pro Date: September 2019 Exposure: 18 x 5' = 1.5 hrs |

Messier 104 - Sombrero Galaxy
Sombrero Galaxy' (also known as Messier Object 104, M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo located 31 million light-years from Earth. The galaxy has a diameter of approximately 50,000 light-years, 30% the size of the Milky Way. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. The dark dust lane and the bulge give this galaxy the appearance of a sombrero.
