The field around M17
            is loaded with rich hydrogen clouds, dark dust motes, amongst
            a heavy sprinkle of faint gold and blue Milky Way stars. IC4701
            is the extended cloud to the lower right and M18 at the bottom
            of this frame. The tiny round red patch at the top is Sh2-47.
