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.

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...

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.

Sketch of the Dumbbell nebula (M27) using 130mm Newtonian reflector, 13mm Plössl (50x / 1 degree FOV), no filter. The nebula was obvious using a 32mm eyepiece at 20x. I got the best view using a 13mm eyepiece at 50x. It looked like a misty grey, slightly squashed circle. The brighter central bars were obvious, especially using averted vision. I could see some hint of structure too. I was pleased with my view of M27 despite interference from the bright moonlight on the night of the observation.

M27 or Dumbbell Nebula is a planetary nebula in the constellation Vulpecula, 1,360 light years away from Earth. The remains of the collapsed star, now a white dwarf, is just visible in the centre. Taken in Ortigia Sicily 12 September 2014
Shot over a span of three nights from my backyard, the Dumbbell Nebula looks bright and colorful in a sea of stars. This object is classified as a planetary nebula, implying that it has a dying star in its core.
Having exhausted its primary source of hydrogen about 10,000 years ago, the dying star, a white dwarf star, is fusing helium into heavier elements like carbon and oxygen. The star is no longer massive enough to hold these materials together against the ongoing fusion reactions and we see ionized hydrogen (red) and oxygen (blue-green) dispersing out into space, almost two light years across.
This nebula was imaged using a 9.25" Schmidt-Cassegrain telescope and a 62Mp one-shot-color astro-camera. No filters were used. I live in an extremely light-polluted suburb so I had to sort out only the best 242x60sec subframes to use for stacking in PixInsight. The image was also post-processed in PixInsight using generalized hyperbolic stretch to reveal the details in this distant cloud of gas and dust.

Edited Hubble Space Telescope image of M76, the Little Dumbbell Nebula (which isn't so little). Color/processing variant.
In celebration of the 34th anniversary of the launch of the legendary NASA/ESA Hubble Space Telescope, astronomers took a snapshot of the Little Dumbbell Nebula (also known as Messier 76, M76, or NGC 650/651) located 3400 light-years away in the northern circumpolar constellation Perseus. The photogenic nebula is a favourite target of amateur astronomers. M76 is classified as a planetary nebula. This is a misnomer because it is unrelated to planets. But its round shape suggested it was a planet to astronomers who first viewed it through low-power telescopes. In reality, a planetary nebula is an expanding shell of glowing gases that were ejected from a dying red giant star. The star eventually collapses to an ultra-dense, hot white dwarf. M76 is composed of a ring, seen edge-on as the central bar structure, and two lobes on either opening of the ring. Before the star burned out, it ejected the ring of gas and dust. The ring was probably sculpted by the effects of the star that once had a binary companion star. This sloughed-off material created a thick disc of dust and gas along the plane of the companion’s orbit. The hypothetical companion star isn’t seen in the Hubble image, and so it could have been later swallowed by the central star. The disc would be forensic evidence for that stellar cannibalism. The primary star is collapsing to form a white dwarf. It is one of the hottest stellar remnants known at a scorching 120 000 degrees Celsius, 24 times our Sun’s surface temperature. The sizzling white dwarf can be seen as a pinpoint in the centre of the nebula. A star visible in projection beneath it is not part of the nebula. Pinched off by the disc, two lobes of hot gas are escaping from the top and bottom of the ‘belt’ along the star’s rotation axis that is perpendicular to the disc. They are being propelled by the hurricane-like outflow of material from the dying star, tearing across space at two million miles per hour. That’s fast enough to travel from Earth to the Moon in a little over seven minutes! This torrential ‘stellar wind’ is ploughing into cooler, slower-moving gas that was ejected at an earlier stage in the star’s life, when it was a red giant. Ferocious ultraviolet radiation from the super-hot star is causing the gases to glow. The red colour is from nitrogen, and blue is from oxygen. The entire nebula is a flash in the pan by cosmological timekeeping. It will vanish in about 15 000 years. [Image description: A Hubble image of the Little Dumbbell Nebula. The name comes from its shape, which is a two-lobed structure of colourful, mottled glowing gases that resemble a balloon that has been pinched around a middle waist. Like an inflating balloon, the lobes are expanding into space from a dying star seen as a white dot in the centre. Blistering ultraviolet radiation from the super-hot star is causing the gases to glow. The red colour is from nitrogen, and blue is from oxygen.]
Sagitta is a tiny constellation shaped like an arrow. It's not hard to see in the actual sky, but it's difficult to pick it out against the background stars here.
The Dumbbell Nebula is also visible in this shot. It was stunning in my 8" Dob.
The Little Dumbbell Nebula (also known as Messier 76, NGC 650/651, the Barbell Nebula, or the Cork Nebula) is a planetary nebula in the constellation Perseus. It was discovered by Pierre Méchain in 1780 and included in Charles Messier's catalog of comet-like objects as number 76. It was recognized as a planetary nebula in 1918 by the astronomer Heber Doust Curtis.
M76's distance is not well known, with estimates ranging from 1,700 to 15,000 light years, and consequently its dimensions are also not well known. The nebula shines at an apparent magnitude of +10.1 with a central star of magnitude +16.6. This star, whose expanding outer layers form the present nebula, has a surface temperature of 60,000 kelvins.
The Little Dumbbell Nebula got its name from its resemblance to the Dumbbell Nebula (M27) in Vulpecula. It was originally thought to consist of two separate nebulae and was thus given two catalog numbers in the NGC, 650 and 651. It is one of the faintest and hardest to see objects in Messier's list.
