This region of the sky encompasses portions of the constellations Scorpius
and Ophiuchus. Rho Ophiuchus is the triple star embedded in blue nebulosity near
the top center. The bright red star just below center, and embedded in orangish
nebulosity is Antares. The large globular cluster M4 is just to the right of
Antares, and a smaller globular (NGC 6144) is just to the upper right of
Antares. Further to the upper right of Antares is the bright star Sigma in
Scorpius. It is also surrounded by a nebula. Above Antares, a number of dark
nebula can been seen silhouetted against the starry background. A third globular
cluster, M80, is to the right of Rho Ophiuchus.
