Dumbbell Nebula (M27)
A composite of 60xL 20xR 20xG 19xB forty five second exposures thru my Meade LX200 telescope using my Meade DSI Pro imager. The individual captures were calibrated using bias frames, dark frames and flat frames and then stacked and processed using Stark Labs' nebulosity and Adobe's Photoshop software. The telescope was guided during the exposures by an Orion 80mm Short Tube telescope with a Meade DSI imager driven by Stark Lab's PHD autoguiding software. All light frames were taken through a set of Meade LRGB CCD filters. Light frames were imaged on October 3, 2008 between 8:11 PM and 10:11 PM near Ellenville, NY. The total exposure was 89 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☉

More red while trying to keep the nebula's blue, more faint stuff - not quite sure which version I prefer.

Jonathan Fay loves this Messier Object because of the symmetry - there is a dumbbell on either side of the telescope.

M27 (NGC 6853), auch bekannt als Hantelnebel, ist ein planetarischer Nebel im Sternbild Füchschen (Vulpecula).
Er ist etwa 1.200 Lichtjahre entfernt und stellt die abgestoßene Hülle eines sonnenähnlichen Sterns dar, der sein Lebensende erreicht hat.
Seine charakteristische Form und die farbigen Gasstrukturen machen M27 zu einem beliebten Beobachtungsobjekt.
English:
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.

A quick process of M27 from July 10th. Finally got a clear sky. Unfortunately it clouded up after an hour so I only got a few subframes. More for the next night then ;-)Taken with a Megrez 90fd and sac10 imager. Guided with an ASTSC15 Astronomiser B&W Toucam and Zenithstar 66sd on an ASGT mount.12x150 secondsIDAS-LPS P1 filter

Don't know what i was thinking, but i wanted to challenge myself. In retrospect that was stupid!
I recently bought a used VMC95L with the goal of using it for guide scope. Well since the auto-guider has still !!! not arrived, i decided to see what this thing could do.
Well as you can imagine, f/11 is pretty dark, for even the brightest DSO. It's pretty much useful for only moon/planetary work.
My polar alignment was not so great, the scope looks to be out of alignment too, and also my 12v battery pack was dying. All in all a pretty lazy effort. But this was nothing serious.

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 particular atoms and ions. In this three-colour composite, a short exposure was first made through a wide-band filtre registering blue light from the nebula. It was then combined with exposures through two interference filtres in the light of double-ionized oxygen atoms and atomic hydrogen. They were colour-coded as “blue”, “green” and “red”, respectively, and then combined to produce this picture that shows the structure of the nebula in “approximately true” colours.They are three-colour composite based on two interference ([OIII] at 501 nm and 6 nm FWHM — 5 min exposure time; H-alpha at 656 nm and 6 nm FWHM — 5 min) and one broadband (Bessell B at 429 nm and 88 nm FWHM; 30 sec) filtre images, obtained on September 28, 1998, during mediocre seeing conditions (0.8 arcsec). The CCD camera has 2048 x 2048 pixels, each covering 24 x 24 µm and the sky fields shown measure 6.8 x 6.8 arcminutes and 3.5 x 3.9 arcminutes, respectively. North is up; East is left.

The dumbbell nebula M27 or NGC 6853 is a 7.5 mag bright planetary nebula with a surface area of 8.0 × 5.7 arc minutes in the constellation Vulpecula. The central star is a white dwarf of 14 mag and a temperature of over 100,000 Kelvin. The distance is around 1400 light years. It got its name from Sir William Herschel because of its elongated shape. The nebula extends by 6.8 arcseconds per century. The dumbbell nebula was discovered by Charles Messier on July 12, 1764.
