NGC281 in the center
            is surrounded by a huge background glow of more red hydrogen.
            In the upper left we find the Owl cluster NGC457 and finally
            to its left the Dolphin nebula Sharpless 2-188. Who could have
            guessed there was so much nebulosity in this part of the sky?!
