M27, The Dumbbell Nebula in Vulpecula by pommierr
M27 lies about 1200 light-years from Earth and has a diameter of about 2.4 light-years. It's expansion rate indicates that the red giant that spawned it erupted between 3000 and 4000 years ago. The white dwarf remanant of the red giant lies at the center of the nebula. Sub-frames were 30-second unguided exposures calibrated with dark, flat and bias frames.
