This amazing complex of dark nebulae and dust in Sagittarius and Ophiuchus lies near the central bulge of our own galaxy, the Milky Way. Dark nebulae are non-luminous clouds of obscuring matter and dust which block the light from stars behind them. Many of the dark nebulae seen here are listed in E.E. Barnard's catalog of dark nebulae and are given a "B" designation, such as B72, the Snake Nebula. Almost the entire complex of dark nebulae seen on the right hand side of the image make up the "Dark Horse and Rider". The Pipe Nebula, Lynds Dark Nebula 1773, comprises the hind quarter and back leg of the Dark Horse, which is seen vertically in this image. B63 is the front leg, B270 is the Horse's head, and B276 is the Rider's head. The area is also filled with star clouds, bright emission nebulae such as M8 - the Lagoon Nebula, M20 - the Trifid Nebula, and M17 - the Omega Nebula. The small Sagittarius star cloud, M24, is at the upper left, and the large Sagittarius star cloud at lower left. The center of our galaxy lies near the bottom edge of the image.
