Rho Ophiuchus Nebula Complex - Another Canon 10D digital SLR 'piggy-back' image'. The central feature of this image looks like a pentagon of stars. The yellow star at the bottom left is Antares, a red supergiant. At the bottom right is globular cluster M4. Rho Ophiuchus is visible above the top of the pentagon in the blue nebulosity. Two prominent dark nebulae,B44 and B45, can be seen streaming upward and towards the left side of the image. 

This shot is a mosiac of one image with a wide FOV and another image much tighter on the area around Antares. The wide FOV was 9 minutes at f/4.5 and the tight FOV was 16.5 minutes at f/5.6

*************

The dark nebulae shown here are part of the Rho Ophiuchus Nebula Complex. Located along the border between the constellations Scorpius and Ophiuchus, this area is rich in color due to the variety of nebulae in this region. There are emission nebulae glowing with the red color characteristic of ionized hydrogen. Reflection nebulae cast a bluish color and a rare yellow reflection nebula is illuminated by the light of Antares, located just out of the frame near the bottom center.

Imaged with my ST-7ME/CFW-8A with the Tru Balance color filter through a Soligor 135mm camera lens attached to a Johnson Widefield Adapter. Sub-exposures were 2 minutes each for a total of 10 minutes LRGB.
