NGC 6818 Planetary Nebula 
At 48 arc sec in size, NGC 6818 is just about the same size as the planet Jupiter.  The images show a definite blue color and the nebula is bright enough to be seen in a six to eight inch scope.  The internal structure can be seen in my image, and of course much more clearly in the HST images.  It's about 10 degrees from the Globular cluster M75.  Use 150-200 power to see it visually.
