Lyra and Vega are clearly visible in this shot. They are to the left of Half Dome and up from the horizon about twice the height of Half Dome.
Part of Hercules is just above Half Dome (lamda, mu, xi, nu and omicron; xi, nu, omicron and another star form the little quadrilateral straight above Half Dome), extending to the top of the shot. Unfortunately, the Key Stone (and M13) is just a bit out of the shot.
Two stars of Cygnus are visible above and to the right of the right-most hemispherical dome on the left side of the pic. Deneb is the lowest star, near the horizon, then there is a reddish double (omicron 1 Cygni and omicron 2 Cygni) above and to the right, then delta Cygni (right arm of the Northern Cross; left wing of the Swan).
Continuing to the left, part of Cepheus is visible at the right edge (alpha Cephei is the brightest star on the left side of the image), eta Cephei continues to the right and up a little, followed by theta a little to the right and up. Mu Cephei, the famous "Herschel's Garnet Star" is visible as a reddish star almost directly below alpha.
Part of Ophiuchus is visible: alpha Ophiuchi is the bright star at the right of the image.
