This stunning object is a very dim perfectly formed ring planetary nebula, at a faint 13.7 integrated magnitude. The 15.6 magnitude blue central star is perfectly centered in this remarkable object. It is big too, spanning 3 arcmins in diameter, and has a splendid turquoise coloration. There are numerous anonymous galaxies in this field. Two are inside the nebula itself, one is located 8:00 near the rim, and at the very top right on the rim is a fainter one. A subject for a much larger telescope might be the galaxy cluster located to the lower right, just to the right of the bright star. This anonymous chain seems to have quite a range of colors from reds to bluish.
