I took up astro photography in January 2010, and after a steep learning curve and slowly acquiring gear when I can afford it, I have a simple(ish) low(ish) cost set up.
This is my second image taken after I had the IR filter removed from my camera, taken over several nights due to having to wait for the target to emerge from behind trees at around 2am.

The second nebula I ever observed through my telescope, and the first object I photographed whilst using a guide scope.
Shot under intense light pollution and periodic cloud, this was a tricky, but worthwhile shot, indeed remains one of my favourite nebulae.
The Dumbbell Nebula (also known as M 27, or NGC 6853) is a planetary nebula (PN) in the constellation Vulpecula, at a distance of about 1,360 light years.

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 1360 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 great observing target in amateur telescopes.
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.

Comparison between a synthetic RGB made from H-Alpha/OIII and a "real" RGB taken without filters.
Even with 12nm narrowband filters it is extremely hard to pull out the outer halo from M27.
Exposures were:
200min H-Alpha 12nm,
235min OIII 12nm
with 10 and 15min subs.
Equipment: 500Da + EF 5,6/400mm L at f5,6/ISO 800, mounted on Avalon Linear.
The RGB from 2011 was made from only 92min exposures (2min subs) with same lens, but 1,4x Kenko Extender (f8,0/560mm), mounted on Astrotrac.
This is a planetary nebula, even though it has nothing to do with planets. Before we had powerful telescopes, astronomers saw these fuzzy little blobs and thought that they might be other planets. We now know them to be remnants of stars that have shed their outer layers and now display vivid colors. This is the likely fate for our own Sun as it enters the final stages of its life.
In order to get this image, I did connect a camera to one of my telescopes. I took 60 1-minute exposures and combined (or stacked) them into one final image. This stacking process allows the natural colors of the image to show up. If you were to look at this in a telescope, you would not see any color unless you had a very large telescope and you were in a location with very dark skies.

Another bubble - but a different sort: M27, the Dumbbell nebula, an ageing star shedding its outer layers (not unlike the Sun will do in a few billion years). This one is about 8 hours of BVR and narrowband filters, taken with my 11" Celestron EdgeHD partly in France and partly in the backyard the past weeks. More would be better, but there are only so many clear nights.
The nebula is about 1200 light-years away and has a diameter of about 1.5 ly (remember, getting to our outer planets is only around 5 light-hours, so you can imagine how big this is: our whole solar system would be nearly lost in the glow of the central star). It is almost certainly not older than 14000 years, and more like 9000, but estimates vary widely and are not certain.
Mais uma captura da M27, a nebulosa do haltere. Ela é grande no céu e bem brilhante, podendo ser vista pela ocular do telescópio e até algumas buscadoras como um brilho bem difuso, uma fumaça circular no céu. Capturá-la em imagens não é difícil, sendo um dos meus primeiros alvos quando estava iniciando. Agora fiz nova captura e muito melhor que a anterior. A foto foi tirada a partir de um local bortle 8.
Another capture of the M27, the Dumbbell Nebula. It's big in the sky and quite bright. It can be seen in a telescope and even some finderscopes as a circle of grey gas. Capture it is not hard at all, and it was one of my first targets when I was starting at the hoby. Now I made a new one and way better. The picture was taken from a bortle 8 site.

The Messier Catalog, sometimes known as the Messier Album or list of Messier objects, is one of the most useful tools in the astronomy hobby. In the middle of the 18th century, the return of Halley's comet helped to prove the Newtonian theory, and helped to spark a new interest in astronomy. During this time, a French astronomer named Charles Messier began a life-long search for comets. He would eventually discover 15 of them. On August 28, 1758, while searching for comets, Messier found a small cloudy object in the constellation Taurus. He began keeping a journal of these nebulous (cloudy) objects so that they would not be confused with comets. This journal is known today as the Messier Catalog, or Messier Album. The deep sky objects in this catalog are commonly referred to as Messier objects.
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888 as a new version of John Herschel's General Catalogue of Nebulae and Clusters of Stars. The NGC contains 7,840 objects, known as the NGC objects. It is one of the largest comprehensive catalogues, as it includes all types of deep space objects and is not confined to, for example, galaxies. Dreyer also published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues, describing a further 5,386 astronomical objects.
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..

The Dumbbell Nebula (M27) captured from London on June 30th 2015. This is my first attempt at imaging using a guide scope to get longer exposures and I'm quite pleased with the result. Up until now most of my images have been made with exposures of 30 seconds or less at ISOs of 3200 or 6400. This image consists of 19 two minute exposures at 800 ISO and it looks much better and was far easier to process. So I'd say this was a successful experiment and it's real relief to have made some progress with guiding which has baffled me for for my last two outings with the scope.

This is my first composite LRGB deepsky image. I do not have the right equipment to make this kind of photography (for example, I have no guide), but nevertheless last summer I decided to take a shot with a famous and bright object.
So, here it is: the Dumbbell Nebula, a planetary nebula in the constellation Vulpecula! Each channel is made of 20 stacked frames, taken with an exp. time of 15 sec. and gain 300.

The Dumbbell nebula is a planetary nebula about 900-1200 light years away. When large stars die, they explode in a cataclysmic supernova. When smaller stars like our own sun die, they just kind of go *poof* and make pretty nebulas like this. They are called a planetary nebulas (nebulae? whatever), but planetary nebulas have nothing to do with planets. There's a central star in the dumbbell that emitted all this crap in both directions. Each end of the nebula has red "weights" , but they're nearly invisible in this picture, probably due to the lack of imaging time and the infrared filter on my digital camera. (The full moon didn't help either) In about 5 billion years, our sun will make its own planetary nebula.
As far as I can tell, the "bright" star on the left is an unnamed mag 5.7 star (just barely visible with the naked eye from a dark location)

Since I have been utterly unable to do any reasonable deep sky imaging at all due to weather and unfavorable conditions over the last couple nights, I decided I'd revisit some of my old output *.TIF files from last fall's sessions, and retouch up on new processing techniques. The first one I thought I'd touch up on, is a data set of Messier 27 - the Dumbbell Nebula, that was grabbed over the course of two nights last September.

The Dumbbell Nebula is a planetary nebula located in the constellation Vulpecula. It was the first planetary nebula discovered by Charles Messier and in the northern sky it is visible with simple binoculars, though it is quite difficult to see from southern latitudes.

M27, also known as the Dumbbell Nebula, is a planetary nebula located 1,360 light years from Earth. The nebula is what is left after a star similar to our Sun gets closer to the end of its life. After expanding and becoming a 'red giant', the outer layers of the star are ejected becoming the shell shown in this picture.
At the center of the nebula, the star is now a 'white dwarf', having just a fraction of its original size. It emits ultraviolet radiation, which ionizes the ejected shell and making is visible to us

I've never been able to find this thing from a dark sky--I just couldn't find the pointer stars in Sagitta among the background stars in the region. I had no trouble at all from my own backyard, however--the fainter background stars were invisible. At least light pollution has this dubious benefit.
