The First Group
030: Andromeda, Cassiopeia, Perseus, Triangulum
The first group of Messier objects we’ll look at are in Andromeda, Cassiopeia, Perseus, and Triangulum. You shouldn’t have much problem orienting yourself to find this group of objects, because Cassiopeia is easy to find, even under bright skies.
This first group comprises eight Messier Objects: three galaxies in Andromeda, a galaxy in Triangulum, two open clusters in Cassiopeia, and an open cluster and planetary nebula in Perseus. We’ll kick it off with one of the most famous Messier Objects, the Andromeda Galaxy, which has been known since ancient times.
