Sharpless 2-24 in Ophiuchus
            is a small molecular cloud in Ophiuchus shaped like the state
            of California which is very seldom imaged due to its extreme
            faintness. A yellow brown hue from all of the carbon and silicate
            dust makes it blend right in to the nearly overpowering sky glow
            from nearby towns.
