This
            extensive field of nebulosity centered on M78/NGC2071 shows the
            full extent of the huge amount of hydrogen gas in this part of
            the sky. From the blues and violets of the central reflection
            nebulosity to the pinks and reds of the surrounding excited hydrogen,
            this part of the MilkyWay is worth revisiting time and time again!
