NGC 6853 (M27) - Dumbbell Nebula

This is the first image i took with the current equipment C6-ngt and the Imaging Source CCD. It is heavily edited and not a very good job i guess, but still..

Info
The Dumbbell Nebula (also known as Apple Core Nebula, Messier 27, M 27, or NGC 6853) is a planetary nebula in the constellation Vulpecula, at a distance of about 1,360 light years. This object was the first planetary nebula to be discovered by Charles Messier in 1764. Planetary nebula are shells of gas shed by stars late in their life after using up all of their nuclear fuel. The star then ejects a significant portion of its mass in a gaseous shell, which is illuminated by its extremely hot central star, which is just the core left from the original star. This a normal process for stars in a late period of their life which also our sun will undergo in a few billion years. Planetary nebulae do not last long in cosmic terms, the shell of gas expands and diffuses becoming invisible and the star turns into a white dwarf. Most planetary nebula are bipolar, meaning symmetric with respect to one axis which is thought to be the rotation axis of the original star.
