Sharpless2-264 in Orion
            is sometimes called the "Angelfish Nebula" because
            short exposures show the shape of a side view of such a watery
            creature. This very deep shot is is more circular in proportions,
            and shows that this nebula is immersed in a lot of yellow and
            blue dust.
