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.

NGC 253: A Starburst Galaxy in Sculptor
The Silver Coin Galaxy, or NGC 253, located 11.4 million light-years away in the constellation Sculptor, is a prominent starburst galaxy notable for its intense star formation. Discovered by Caroline Herschel in 1783, it captivates astronomers and stargazers alike, showcasing dynamic stellar activity and vibrant colors through advanced imaging techniques.
NGC 4565: The Needle Galaxy
The post discusses the Needle Galaxy (NGC 4565) located in the Coma Berenices constellation, notable for its thin, edge-on spiral structure. It features a sketch of the galaxy as it appears through a telescope along with a photo from a Seestar S50. Also known as Caldwell 38 (C38). The article also mentions and shows NGC 4562 nearby.

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.
NGC 3115: The Spindle Galaxy with a Supermassive Black Hole
Within the constellation Sextans, the Spindle Galaxy, or NGC 3115, is observed edge-on from Earth, displaying a lens-like appearance. Discovered by William Herschel in 1787, it is a lenticular galaxy with a central bulge housing a supermassive black hole. Despite its massive size, the black hole shows subdued behavior, emitting faint radiation. Observations in March 2024 in Seattle revealed its distinct appearance, in line with previous descriptions.
Messier 71 (NGC 6838): A Globular Cluster Close to Home
Globular clusters like Messier 71 (M71) make for great targets. With a pair of binoculars away from bright city lights, an observer can see M71 as a fuzzy patch. Move up to the telescope (say 4 inches in diameter and larger), and you can start to make out some individual stars. For a long time,ContinueContinue reading “Messier 71 (NGC 6838): A Globular Cluster Close to Home”
