The Double Cluster is easily visible to the naked eye even from moderately light-polluted locations. They are a beautiful sight in a telescope at low power. NGC 869, also known h Persei, is on the left, with NGC 884, also designated chi Persei, on the right. They are both located in close proximity towards the Perseus arm of our galaxy at a distance of 7000 light years, and are very young for galactic star clusters, NGC 869 being 5.6 million years old, and NGC 884 being 3.2 million years old. Each contains more than 100 stars. Their appearant size is 30 arcmin each, about the diameter of the full moon.
