The Double Cluster located in Persus is a combinaton of two clusters, NGC 884 and NGC 869. Each cluster is relatively young at 3.2 and 5.6 million years old. Between the two clusters there are over 300 blue-white giant stars. From a dark sky, the two clusters can be seen as a hazy patch located between the constellations Cassiopia and Persus.
