There are few objects
            in the sky as amazing as a hot OB type star blowing huge amounts
            of hydrogen at a high velocity into the interstellar medium.
            The
            hot stellar wind that drives this nebula is just below center,
            the 7.2 magnitude type O4 known as HD 192163.These object known as Wolf-Rayet Bubbles
            are rare in the sky, and this one is amongst the best. Also known
            as Sharpless 2-105, this bubble is 18 arcminutes in size.
