Dumbbell Nebula – Messier 27

The Dumbbell Nebula (Messier 27 or NGC 6853) is a planetary nebula in the Vulpecula constellation, at a distance of about 1360 LY. Its central region contains the largest known white dwarf star.

For this image I used three 240 second exposures on Lightbuckets LB-0003 with the following filters:
Hydrogen-Alpha in Green
Sodium II in Red
Oxygen III in Blue

MaximDL was used to stack, align and screen stretch. The image was then cropped using Gimp.
