The Dumbbell Nebula (M27 or NGC 6853) in Vulpecula was discovered in 1764 by the French astronomer Charles Messier. This planetary nebula lies at a distance of approximately 1,200 light years and is estimated to be approximately 3,500 years of age. The luminous )main) body of the planetary is approximately 6 arc-minutes in diameter and the halo surrounding it is approximately 15 arc-minutes. While observing the Dumbbell Nebula I noted bright knots within the main body of the nebula, especially over the eastern half of the nebula (as visible in the inset sketch at 210x). This was one of my best views of the Dumbbell Nebula to date.
