IC4592, the "Blue
            Horse Head Nebula" in Scorpius also has a body as seen here
            in this 135mm shot. You can see the neck with a flowing brown
            dusty mane, the front of his torso, and one leg at the bottom
            of the frame. The "Flying Bat Nebula" is also seen
            here on the lower right. The blue wisp on the right edge is LBN5,
            a very dim blue reflection nebula.
