NGC 2392, the "Eskimo" nebula, is a very small but rather bright planetary nebula.  It is visible from light-polluted areas.  High magnification and steady skies are needed to see details (I have not personally seen them).  Its apparent size from Earth is comparable to the planet Jupiter.  The image below came out surprisingly well considering that I don't use adaptive optics.  This was processed using AstroArt's maximum entropy deconvolution filter with many iterations. You will notice a halo around a nearby star, which is an artifact from the image processing.
