Hercules rises on its side.
The 4-star "Keystone" contains the famed globular
cluster M 13. Kornephoros is the brightest star,
Zeta Herculis number two. Rasalgethi, the Alpha star, marks
Hercules' head. Hercules' other bright globular cluster M 92 is
not visible to the naked eye. More of the classic constellation can be
seen in the view shifted to the west.
Hercules also has a star with an orbiting planet.
