I came across this tiny planetary while on a star-hop around Perseus with my Revolution Imager 2 video camera. On this image scale it shows its beautiful color and just a hint of structure. Almost lost amongst the stars of the Milky Way, NGC 7048 is an estimated 6,000 light years away and is approximately 2 light years across, making it about the same physical size as the much closer M27, the Dumbbell Nebula.

Neat stuff.
