Perseus double cluster, had still some time left at the end of the night after the main sequence of photos and before dawn so I took the opportunity to capture about 25 minutes of photos of the double cluster. This is a pair of open clusters of stars (NGC 884 left and NGC 869 right), both are composed mostly of young blue giants and a few red giants in NGC 884. Both clusters have most likely formed from a single gas cloud and are only separated by a few hundred light years. This pair of cluster is relatively bright and can be viewed with the naked eye or a pair of binoculars in dark locations, in those cases, the clusters appear as nebulous region, with a couple of stars resolved with binoculars.
