When Geauga Park District Naturalist Chris Mentrek is stargazing at Observatory Park, one of his favorite sights is the Summer Triangle. “The Milky Way stripe goes right through the triangle,” says Mentrek, “and Altair, Deneb, and Vega form its corners. They’re three of the brightest stars and are also points in the constellations Aquila, Cygnus, and Lyra.”
