Messier 100 (NGC 4321): A Grand Design Spiral in Coma Berenices

Messier 100 (M100) is a grand design spiral galaxy located 55 million light-years away in Coma Berenices. Discovered by Pierre Méchain in 1781, it features symmetrical arms with vibrant star-forming regions. M100 is both visually striking and dynamic, making it a favorite for amateur astronomers. This post provides history and personal observations using a Seestar S50. Also known as NGC 4321, UGC 7450, PGC 40153.

Messier 7 (NGC 6475): Ptolemy’s Ancient Cluster Still Shines Bright

Messier 7, or Ptolemy’s Cluster, is a prominent star cluster located in the Scorpius constellation, first recorded by Claudius Ptolemy in 130 AD. This open cluster, visible to the naked eye, contains 80 stars and spans 25 light years. It symbolizes the lasting human fascination with astronomy and the cosmos.

Learn more about the cluster, including a personal observation from Wayne McGraw and photo using a Seestar S50 under suburban skies in Florida.

Messier 25 (IC 4725): A Scattered Jewel in Sagittarius

In the 18th century, Charles Messier cataloged celestial objects while searching for comets, including the beautiful open cluster Messier 25 (M25) in Sagittarius. Approximately 2,000 light-years away, it contains around 600 stars with no nebulosity. M25 is best viewed through binoculars or low-power telescopes during summer nights, offering a delightful starry tapestry. Also known as M25, IC 4725, Melotte 202

Messier 22 (NGC 6656): A Cosmic Heavyweight Just Off the Teapot

Messier 22 (M22) is a bright and nearby globular cluster in Sagittarius, notable for its unique features such as a planetary nebula and two black holes. Discovered by Abraham Ihle in 1665 and later cataloged by Charles Messier in 1764, M22 provides insights into the early Milky Way and is ideal for observation. Also known as NGC 6656.

Messier 17 (NGC 6618): The Enchanting Swan Nebula

In the vast expanse of our Milky Way galaxy, amidst a sea of stars, lies an ethereal celestial beauty known as Messier 17 (M17), or more commonly, the Swan Nebula. Named after its graceful swan-like appearance, this stellar nursery lies in the summer southern constellation of Sagittarius.

Messier 33 (NGC 598): The Triangulum Galaxy—A Pinwheel in the Sky

Discover the breathtaking beauty of Messier 33, the Triangulum Galaxy! As one of the closest galactic neighbors to the Milky Way, Messier 33 known as the Triangulum Galaxy dazzles with its stunning spiral structure. See what it looks like in a telescope and when photographed with a Seestar S50. Also known as M33, Pinwheel Galaxy, NGCs 588, 592, 595, and NGC 603

Messier 106: A Galaxy with Unique Arms in Canes Venatici

Within the constellation Canes Venatici, or NGC 4258, is Messier 106 with it’s arms made of gas and dust. Most observers with a modest telescope can make out Messier 106’s relatively bright and distinct structure. And speaking of structure, one of the most fascinating aspects of M 106 is its unique arms. Unlike typical spiral galaxies where the arms are composed mainly of stars, the extra arms of M106 are composed of vast amounts of gas.
