Breathtaking image of the Double Cluster (h and chi Persei, NGC 869 and NGC 884) in the constellation Perseus. These two open star clusters, visible to the naked eye under dark skies, are only a few hundred light-years apart and share a similar age, suggesting a common origin. Cataloged by Hipparchus in 130 BC, they're a stunning binocular target, showcasing bright, young stars against the backdrop of the night sky.

Stunning image of the Double Cluster (NGC 869 & NGC 884) in the Perseus constellation. These two open star clusters, easily visible with binoculars, are only a few hundred light-years apart and share a similar age, suggesting a common origin. Cataloged by Hipparchus in 130 BC, they are a breathtaking sight from dark skies, showcasing a rich tapestry of young, hot stars against the backdrop of the cosmos.
