The Rho Ophiuchi region is a confused mass of gas and dust just above Antares and the head of Scorpio. This extensive nebula complex is far larger than the single frame shown here, extending far to the east into Sagittarius.
Rho Ophiuchi itself is the triple star seen here at the top center of the image, at the center of a bright reflection nebula. The double at lower center is Iota Scorpii and the star Al Niyat is on the right side. Also notable are the dark clouds of dust and gas that block the light of the stars and nebula behind creating black voids in the starfield.
This area is quite colorful, with both the blues of reflection nebulae and the reds of emission nebulae. I have gathered some color data but need more before assembling a proper color image of this region.
