Hercules
The Hercules is a fairly large constellation in summer, but isn't very obvious. "Hercules" is a name of Greek hero, and the constellation is represented as a kneeling man with his head turning south. Though the constellation is faint, a fairly strained shape of "H" that forms Hercules' body is a good mark to find that. Alpha Herculis, Ras Algethi, is positioned at the kneeler's head has a magnitude of 3, ancient Chinese had regarded the star as the Emperor's seat, and they had observed this field very carefully whether there was any novae or comets.
