NGC 246 is a rather lonely and large planetary nebula in Cetus. In this example the distorted sphere of gas has many thin and thicker regions giving it an irregular "texture." Like most spherical clouds of gas the outer edges seem brighter than the center which appears void. This is a perspective effect in that more line-of-sight gas is observed towards the outer portions. This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014.
