The Dumbbell Nebula (M27)
Posted by Robert's Photos (Eau Claire, United States) on 21 March 2007 in Miscellaneous and Portfolio.
The star in the center has exhausted its core fuel but continues to burn helium at the surface therefore shedding its outer layer into space, igniting surrounding elements such as hydrogen. Exp.time: 40 x 4min = 2:40min @ ISO800. Modified Canon 300D. www.RobsAstroimaging.com
