Located in the constellation of Perseus are the two open clusters of NGC 869 and NGC 884. Both are at a distance of around 7,500 light years away. Both are a relative young age of 13 million years. The clusters are separated by a few hundred light years. Each cluster consists 300 to 400 stars with NGC 869 being slightly brighter and more compact.

Messier 52 is an open cluster located in Cassiopeia. It contains around 193 members. Its estimated distance is between between 3,000 and 7,000 light years. The differences in distances are due to a large amount of interstellar dust in that direction that varies the brightness by an unknown amount.

Messier 45 or as it is often called, The Pleiades. The name is possibly derived from ancient Greek word "plein" meaning to sail. It is often called the Seven Sisters as the brightest stars are named for the Greek mythological sisters of Atlas and Pleione, Alcyone, Electra, Maia, Merope, Taygeta, Celaeno, and Asterope or Sterope.
The reflection nebula around the cluster was originally thought to be left over dust from the clusters formation, but due to the age of the cluster, that nebulosity would have been dispersed. It seems it is just passing through an dusty region.
The cluster is an estimated 444 light years away, contains over 1,000 members and a large number of brown dwarf objects. Like most clusters, it will slowly disperse over millions of years. The cluster's age is estimated to be between 75 and 150 million years old.

North of the Double Cluster is a sparse open cluster called Stock 2, or sometimes called the Muscle Man Cluster. It is said to resemble a stick man figure flexing their biceps. It contains some 50 stars and is located around 1,000 light years distant.
