This
            magnificent "Cornflower Blue" planetary is roughly
            horseshoe shaped and of a very low surface brightness. Listed
            at around 15th magnitude, the central star seen clearly here
            in the center as a blue object is 16th magnitude. At 5 arc minutes
            in size, this is about half the size of the globular in Hercules,
            M13. Ive posted two images here. The upper image is the direct
            shot, and the lower is labeled. Identifying the small objects
            in the field is half the fun! Ive circled all the faint 18th
            and 19th magnitude galaxies plotted on Cartes du Ciel, and found
            one asteroid at the bottom, which is nameless - just has a numerical
            designation. It is in the 20,000 range number wise and is currently
            at 19.1 magnitude.
