M27 Dumbbell Nebula

Here is the famous M27, the Dumbbell Nebula, which is a planetary nebula located in the constellation Little Fox about 1227 light years old and 3000 to 4000 years old.
The heart of this object is particularly bright and has an apparent diameter that reaches 1/5 that of the Moon. Much less shiny extensions require long hours of poses and deploy around the center dumbbell.
The central star (at the origin of the nebula) has become a very hot (85,000 K) white (blue) dwarf.

21h40 exposures at the end of August and the beginning of September for this version where the most distant and tenuous extensions of the nebula are revealed
RGB poses were done to obtain the natural color of the stars.
