This is just part of the 4.6 arcminute image produced by the Faulkes Telescope. This planetary nebula consists of a small dense nebula of about 16" x 26" in diameter, surrounded by a fainter envelop measuring about 40 x 35 arc seconds. The bright inner nebula is described as looking like an eye by Burnham, and the outer shell gave rise to its popular name, as it is of about the apparent size of Jupiter.
Alan has used a High Pass filter to sharpen up the image.
