Here's a beautiful target in Taurus - a small planetary nebula formed from a rapidly-orbiting (4-9 day period) double star system, the progenitor of which was originally about 4.5 solar masses.  The bright central star is an AO III giant, whereas the progenitor is a now a small O-type, sub-luminous dwarf. 


This planetary was discovered by William Herschel in 1790, and it caused him to reconsider his hypothesis that all nebulae were clouds of unresolved stars.  It is about 800 light-years from us.
