I went out to my first astronomy club observing night this year. Nice clear sky before the clouds rolled in at 11 p.m. We lucked out and found Comet Garradd was passing by M71, a small globular cluster in Sagitta. The comet is the small greenish orb with the bright centre and is located just above the globular cluster.
I also managed to get Brocchi's Branch (the upside-down Coat Hanger) in the upper-right quadrant and in the upper-left quadrant M27, the Dumbbell Nebula.
This is a stack of six 10-second exposures imaged with a Nikon D200 DSLR and a Nikkor 85mm f/2 AIS lens.
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.
M27: The Dumbbell Nebula, a planetary nebula in the constellation Vulpecula, is approximately 1,360 Light Years away.

This is M27, the dumbbell Nebula. Taken with a Meade LX200 10" f10 SCT telescope at prime focus with an unmodified Canon XTi 400D DSLR. This is a combination of 27 light , 27 dark, and 27 bias frames. Guiding was done with PHD software using an Stellarvue AT1010 80mm Achromat and a SuperCircuits PC164 Video Camera. Processing was done using ImagesPlus 2.82 and Adobe PhotShop CS software.

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.

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. .
.
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.

Updated with Darks and Flats. I pretty much pump out as much as i could with this one. I simply need more lights. I was shooting until the sky was undoubtedly blue. I think I'm going to do some more work on this one. I've never shot this one much before, but it seems quite interesting. More lights should really bring out more detail.

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.
