M7 is one of the most prominent open clusters of stars on the sky. The cluster, dominated by bright blue stars , can be seen with the naked eye in a dark sky in the tail of the constellation of Scorpius . This color picture was taken in 1995 at the Burrell-Schmidt Telescope at Kitt Peak National Observatory in Arizona . Also visible is a dark dust cloud near the bottom of the frame, and literally millions of unrelated stars towards the Galactic center .
