Astronomy Magazine Picture of the Day July 13, 2007

NGC 6781 is a very beautiful planetary nebula containing a 16.8 magnitude central white dwarf. Much overlooked because of the wealth of bright objects in the vicinity, it is well worth the effort to image. The globe of the nebula is 2 light years wide.
