Here is NGC 6302, the Butterfly Nebula (also known as the Bug Nebula). It has one of the most complex structures ever observed among planetary nebulas. The central star is one of the hottest stars known.

The Butterfly is a tiny creature, only 0.8 arc seconds in width. You need good seeing and a large telescope to acquire a satisfying image. I hope you enjoy it!
