 July 15 2009  M27 - The Dumbbell Nebula |
|
The Dumbbell Nebula (also known as Messier 27, M 27, or NGC 6853) is a planetary nebula (PN) in the constellation Vulpecula, at a distance of about 1,360 light years from Earth.
This object was the first planetary nebula to be discovered by Charles Messier in 1764.
From calculated expansion rates the estimated kinetic age of M27 is roughly 9,800 years. The central White Dwarf star is larger than any other of its kind with an estimated size of .56 Solar Masses.
This is an early morning rise. My house blocks it until the Zenith (roughly 4am). At which time I began quickly began grabbing frames before the sun lights the background sky at roughly 4:15am causing the frames to wash out. As the weeks progress, I should have a better opportunity to get a better run of frames as it will be visible earlier, and therefor under darker skies.
