I find this object much smaller (around 0.3x0.4') than what is suggested by the values in catalogues (0.8x0.8'). It's a fairly blue, very bright planetary with a shape resembles a diamond, divided in N-S direction by a dark belt of matter in the middle. Its name is very felicitous when taking a look at its entire shape: Cheeseburger nebula. I can detect an additional faint nub on the NW part of the object. Requires large magnification and a very calm atmosphere.
