   Explanation: This pretty starfield spans about three full moons (1.5
   degrees) across the heroic northern constellation of Perseus. It holds
   the famous pair of open star clusters, h and Chi Persei. Also cataloged
   as NGC 869 (top) and NGC 884, both clusters are about 7,000 light-years
   away and contain stars much younger and hotter than the Sun. Separated
   by only a few hundred light-years, the clusters are both 13 million
   years young based on the ages of their individual stars, evidence that
   they were likely a product of the same star-forming region. Always a
   rewarding sight in binoculars, the Double Cluster is even visible to
   the unaided eye from dark locations. But a shroud of guitar strings was
   used to produced diffraction spikes on the colorful stars imaged in
   this vibrant telescopic view.
