C22 is a fairly popular planetary nebula for casual observers.

A small refractor will reveal a star-like object with slight nebulosity. A 6 in. telescope with a magnification around 100x will reveal a slightly bluish disk. Telescopes of diameter 16″ or greater may reveal slight colour and brightness variations in the interior.
