Description

M27 "Dumbbell Nebula" RGB crop processed form Alberto Pisabarro's data (thanks, dude).

Colors are not very correct, as well as stars; I will try to improve them in coming revisions.

Afera drastic star erasing, for the next revision I preserved the stars, but i think I've lost some contrast inside the nebula, so the inner structure is not enough visible... well, I'll have to perform another attempt ;-)
