Double Star Cluster in Perseus


The Perseus double cluster consists of two open clusters (NGC 869 and NGC 884) which are physically located close to each other because they were born from the same interstellar cloud. This double cluster can be located with the naked eye, but it is in a pair of binoculars or a small telescope that all its splendor is revealed. It looks like a display of sparkling diamonds.

It is also a beautiful object to photograph when starting out in astrophotography because it is relatively bright and does not require very long exposures.
