Here is our latest shot
            of B72 and companion dark nebulas known as the "Snake with
            Eggs" nebula. The Eggs are B255, B68, B70 and are in a very
            dust obscured Milky Way field. So obscured was it that all the
            stars in the original image were yellow or brown, with no blues.
            Using the Color Correction tool in PI, I was able to restore
            most star colors, yeilding a more natural appearance.
