Description

A popular object at this time of the year, the planetary nebula M27 consists of a glowing shell of ionized gas, which has been ejected from a red giant star in the late stage of its life to become a white dwarf.  The complicated nature of the planetary nebula made processing very difficult, in particular, teasing out the aforesaid but very faint outer fans, which make a big difference to the overfall form.  After considerable experimentation to achieve this outcome I'm happy with the final image, which I hope shows off the said apple core / dumbbell and its outer fans to good effect.
