Van den Bergh 105 and 106 (alternatively catalogued as IC 4603 and IC 4604) are reflection nebulae in the constellation of Ophiuchus. These nebulae form the blue reflection portion of the larger Rho Ophiuchus cloud complex, an often photographed part of the night sky. Surrounding the reflection nebulae are dark molecular clouds of cold hydrogen gas, appearing as silhouetting wisps obscuring the background starlight.
