The dumbbell nebula (M27) near Cygnus. Canon T2i (as I recall it had been recently astro-modded to capture more of the hydrogen alpha line) through 8" SCT.
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. .

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.
This object was the first planetary nebula to be discovered; by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and its diameter of about 8 arcminutes, it is easily visible in binoculars, and a popular observing target in amateur telescopes.

Edited Hubble Space Telescope image of M76, the Little Dumbbell Nebula (which isn't so little).
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.]
M27 dumbbell nebula
The wonderful Dumbbell planetary nebula.
At the center, we observe a star throwing off most of its mass on its way to becoming a white dwarf.
The central star is emitting huge amounts of ultraviolet light which illuminate the nebula.
Remarkably, 90% of the light is emitted in the 500 nm green O-III band.
We also observe an illuminated cylindrical red volume of hydrogen in the nebula. This is a binary system and is rotating.
It is located at a distance of 1360 ly.
The age as roughly 10,000-13,000 years.
it is a popular target, and is visible in binoculars.

The Dumbbell Nebula — also known as Messier 27 or NGC 6853 — is a typical planetary nebula and is located in the constellation Vulpecula (The Fox). The distance is rather uncertain, but is believed to be around 1,200 light-years. It was first described by the French astronomer and comet hunter Charles Messier who found it in 1764 and included it as no. 27 in his famous list of extended sky objects [2] .Despite its class, the Dumbbell Nebula has nothing to do with planets. It consists of very rarified gas that has been ejected from the hot central star (well visible on this photo), now in one of the last evolutionary stages. The gas atoms in the nebula are excited (heated) by the intense ultraviolet radiation from this star and emit strongly at specific wavelengths.This image is the beautiful by-product of a technical test of some FORS1 narrow-band optical interference filtres. They only allow light in a small wavelength range to pass and are used to isolate emissions from particu

A composite of 15xL 15xR 30xG 43xB sixty second exposures thru my Meade LX200 telescope using my Meade DSI Pro III imager. The individual captures were calibrated using dark frames and flat frames and then stacked and processed using Stark Labs' nebulosity software. The telescope was guided during the exposures by an Orion 80mm Short Tube telescope with a Meade DSI Pro imager driven by Stark Lab's PHD autoguiding software. Light frames were imaged on August 17–18, 2009 between 11:28 PM and 1:35 AM near Ellenville, NY. The total exposure was 120 minutes.

M27 Nebulosa Manubrio (Dumbbell nebula)
(integrazione)
Scoperta nel 1764 da Charles Messier che la catalogo' al numero 27 del suo celebre catalogo, la Nebulosa Manubrio è una nebulosa planetaria visibile nella costellazione della Volpetta, distante da noi circa 1360 anni luce.
La sua forma ricorda quella di uno sferoide ed è vista lungo la linea prospettica del piano equatoriale. Nel 1992 fu calcolata la velocità di espansione reale, pari a 31 km/s. Dato che l'asse maggiore ha un raggio di 1,01 anni luce, l'età cinematica della nebulosa sarebbe di 9800 anni
Come in molte altre nebulose planetarie vicine a noi, anche in M27 sono facilmente visibili dei nodi; la sua regione centrale è segnata da un livello di nodi oscuri e brillanti, associati con dei filamenti. I nodi presentano una vasta gamma di morfologie.
La stella centrale è una nana bianca con un raggio di 0.055 ± 0.02 R☉, superiore dunque ad ogni altra nana bianca conosciuta; la massa della stella centrale è stata stimata nel 1999 come pari a 0.56 ± 0.01 M☉
