New Astro Image - Rho Ophiuchi

I finally got a clear night and a chance to image again. Since it is early summer, the constellations Scorpius and Ophiuchus are as high as they get in the southern sky, so I thought I would image again in the area of Rho Ophiuchi and Antares. This area is one of the most colorful in the sky, with a combination of reflection nebulae and emission nebulae. I hope you like it.

This image is of the Rho Ophiuchi region of the sky. The bright star in the lower right is alpha Scorpii, Antares. The triple star system in the upper right, surrounded by blue nebulosity is Rho Ophiuchi. You can also see M4, a Globular Cluster, to the right of Antares.
