I was in two minds whether to put this one up but it's a good representation of how you would see this bright planetary nebula through a pair of binoculars.
The Dumbbell Nebula is located in the constellation of Vulpecula and has a magnitude of +7.3.
10 x 1 minute light-frames @ ISO 800 with a Canon 350D ('unmodded').
Haven't been out with the scope in months. Seeing was crap and cloud reduced the number of shots. The streak is a satellite passing overhead, not a perseid meteorite unfotunately. 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. The central star, a white dwarf, is estimated to have a radius which is 0.055 ± 0.02 R☉ which gives it a size larger than any other known white dwarf.

This is a restacking of the previous image processed on just a portion of the overall image so that I could use the 3x Drizzle setting in Deep Sky Stacker to try and improve the resolution of the nebula.
Also tried a couple new tools in The Gimp for cleaning up noise, setting the black point etc.
The photo consists of 30x 20 second exposures at ISO1600 on a Canon T1i DSLR at prime focus on a 10 inch SN-10AT telescope using a light pollution filter. 10 minutes total exposure time.

This is a crop of the 'widefield' version, I'm very pleased with the amount of detail retained and for just 10 minutes worth of data!

One of my favorite deep space objects is the Dumbbell Nebula. If you look in my photostream you will see other images of this summer time object. It's a planetary nebula - the remains of a star that has died and exploded. Its about 1360 light years away in the constellation of Vulpecula. In the stars death the elements it made during its "life time" in its core will be used to create the next generation of stars.
Its the ultimate in recycling...

M27 (NGC 6853), also known as the Dumbbell Nebula, is a planetary nebula located in the constellation Vulpecula.
It lies around 1,200 light years away and represents the expelled outer layers of a Sun-like star at the end of its life cycle.
Its distinctive shape and colorful gas structures make M27 one of the most observed planetary nebulae in the night sky.

The Dumbbell nebula is a planetary nebula located approximately 1200 light years away.
At the centre of the nebula is a hot white dwarf star. This star is surrounded by a shell of gas which is being excited by the high-energy radiation coming from the white dwarf creating the visible nebula.

The Dumbbell nebula, also known as Messier 27, pumps out infrared light in this image from NASAs Spitzer Space Telescope. The nebula was named after its resemblance to a dumbbell as seen in visible light. It was discovered in 1764 by Charles Messier, who included it as the 27th member of his famous catalog of nebulous objects. Though he did not know it at the time, this was the first in a class of objects, now known as planetary nebulae, to make it into the catalog.
Planetary nebulae, historically named for their resemblance to gas-giant planets, are now known to be the remains of stars that once looked a lot like our sun. When sun-like stars die, they puff out their outer gaseous layers. These layers are heated by the hot core of the dead star, called a white dwarf, and shine with infrared and visible-light colors. Our own sun will blossom into a planetary nebula when it dies in about five billion years.
The Dumbbell nebula is 1,360 light-years away in the Vulpecula constellation, and stretches across 4.5 light-years of space. That would more that fill the space between our sun and the nearest star, and it demonstrates how effective planetary nebulae are at returning much of a stars material back to interstellar space at the end of their lives.
Spitzers infrared view shows a different side of this recycled stellar material. It is interesting how different Spitzers view of the Dumbbell looks compared to optical images, comments Dr. Joseph Hora of the Harvard Smithsonian Center for Astrophysics. The diffuse green glow, which is brightest near the center, is probably showing us hot gas atoms being heated by the ultraviolet light from the central white dwarf.
A collection of clumps fill the central part of the nebula, and red-colored radial spokes extend well beyond. Astronomers think these features represent molecules of hydrogen gas, mixed with traces of heavier elements. Despite being broken apart by the ultraviolet light from the central white dwarf, much of this molecular material may survive intact and mix back into interstellar gas clouds, helping to fuel the next generation of stars. Similar structures are seen in the Helix and other planetary nebulae.
This image was made using data from Spitzers Infrared Array Camera (IRAC). Blue shows infrared light with wavelengths of 3.6 microns, green represents 4.5-micron light and red, 8.0-micron light.
