Edited European Southern Observatory image of the Skull Nebula, just in time for Halloween. Color/processing variant.
Original caption: Captured in astounding detail by ESO’s Very Large Telescope (VLT), the eerie Skull Nebula is showcased in this new image in beautiful pink and red tones. This planetary nebula, also known as NGC 246, is the first known to be associated with a pair of closely bound stars orbited by a third outer star.
Edited Hubble Space Telescope image of the protoplanetary nebula Minkowski 92. Color/processing variant.
The NASA/ESA Hubble Space Telescope has been used to capture a striking image of a rare astronomical phenomenon called a protoplanetary nebula. This particular example, called Minkowski’s Footprint, also known as Minkowski 92, features two vast onion-shaped structures either side of an ageing star, giving it a very distinctive shape. Protoplanetary nebulae like Minkowski’s Footprint have short lives, being a preliminary stage to the more common planetary nebula phase. In the middle of the image is a star, soon to be a white dwarf, puffing out material due to intense surface pulsations. Charged particle streams, called stellar winds, are shaping this gas into the interesting shapes that Hubble allows us to see. Technically speaking Minkowski’s Footprint is currently a reflection nebula as it is only visible due to the light reflected from the central star. In a few thousand years the star will get hotter and its ultraviolet radiation will light up the surrounding gas from within, causing it to glow. At this point it will have become a fully fledged planetary nebula. The processes behind protoplanetary nebulae are not completely understood, making observations such as this even more important. Hubble has already conducted sterling work in this field, and is set to continue. The image was obtained with the Hubble's Wide Field Planetary Camera 2. The picture has been made from many exposures through four different colour filters. Light from ionised oxygen has been coloured blue (F502N), light passing through a green/yellow filter (F547M) is coloured cyan, light from atomic oxygen is coloured yellow (F631N) and light from ionised sulphur is coloured red (F673N). The total exposure times per filter were 2080 s, 960 s, 2080 s and 1980 s respectively and the field of view is only about 36 arcseconds across.
Edited European Southern Observatory image of the Helix Nebula. Color/processing variant.
Original caption: ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA) has captured this unusual view of the Helix Nebula (NGC 7293), a planetary nebula located 700 light-years away. The coloured picture was created from images taken through Y, J and K infrared filters. While bringing to light a rich background of stars and galaxies, the telescope's infrared vision also reveals strands of cold nebular gas that are mostly obscured in visible images of the Helix.
M27 taken on 1st November 2012 with poor seeing conditions. I took this image using my Nexstar 8 GPS with F6.3 focal reducer wedge mounted and guided with a skywatcher synguider. The shot consists of 5No. 5 minute exposures, 5 flat frames and 5 darks, all taken with an un-modified canon 1000d controlled, pre-processed and stacked in Nebulosity and post processed i Photoshop.
Edited European Southern Observatory image of the planetary nebula ESO 378-1.
Original caption: This extraordinary bubble, glowing like the ghost of a star in the haunting darkness of space, may appear supernatural and mysterious, but it is a familiar astronomical object: a planetary nebula, the remnants of a dying star. This is the best view of the little-known object ESO 378-1 yet obtained and was captured by ESOâs Very Large Telescope in northern Chile.
Edited European Southern Observatory image of the star L2 Puppis and its planetary nebula.
Original caption: Some of the sharpest images ever made with ESOâs Very Large Telescope have for the first time revealed what appears to be an ageing star in the early stages of forming a butterfly-like planetary nebula. The observations of the red giant star L2 Puppis from the ZIMPOL mode of the newly installed SPHERE instrument are combined here with infrared data from NACO, also on the VLT, which shows a dust loop deployed on the far side of the upper part of the nebula. The dying stages of the lives of stars continue to pose many riddles for astronomers.

Two sketches of the Dumbbell Nebula, the gentle dying exhalation of a nearby star somewhat like our sun.
Despite the awful skies of Detroit, the shape of the gas shell was very noticeable, and I thought I saw hints of the dimmer outer shroud. I didn't see many stars behind the nebula - I thought perhaps three, near the edges.
An OIII filter seemed to help at the higher power, but after spending several minutes with it I went inside, ruining my dark adaptation. I'm hoping to spend quality time with it next weekend.

NGC3242, the 'Ghost of Jupiter', is a planetary nebula, which is actually nothing to do with planets. These objects could be easily confused for planets through telescopes of the past, hence the name.
This nebula, and other of its kind, are the dispersed mantles of gas from dying stars. They are often quite colourful (this one is blue-green) so I apologise for providing only a (V filtered) monochrome image. The plan was to get the RGB set to make a colour image; I managed G and B but ran out of time before getting the R. This object was imaged in haste at the end of a 30 minute session during which the Faulkes Telescope North was behaving erratically due to recent software 'upgrading'. The intended target was M57 but the telescope just would not point at it. The tiny dot at the lower edge of the nebula is not a star but a hot pixel.

This is my first true deep sky astrophoto, taken as a 10 second exposure at ISO 400 at my 8" f5 Schmidt-Newtonian's prime focus. It's not much, but the Ring Nebula is clearly visible below and right of center. It even shows some red color. I can't wait till I can get out with a dark sky to take some wide-field astrophotos!

Edited European Southern Observatory image of the planetary nebula Abell 33. Color/processing variant.
Original caption: Astronomers using ESO’s Very Large Telescope in Chile have captured this eye-catching image of planetary nebula Abell 33. Created when an aging star blew off its outer layers, this beautiful blue bubble is, by chance, aligned with a foreground star, and bears an uncanny resemblance to a diamond engagement ring. This cosmic gem is unusually symmetric, appearing to be almost perfectly circular on the sky.
Processed version of an image from the Hubble Space Telescope of NGC 6818, a planetary nebula called the Little Gem Nebula.
Original caption: This colourful bubble is a planetary nebula called NGC 6818, also known as the Little Gem Nebula. It is located in the constellation of Sagittarius (The Archer), roughly 6000 light-years away from us. The rich glow of the cloud is just over half a light-year across — humongous compared to its tiny central star — but still a little gem on a cosmic scale. When stars like the Sun enter retirement, they shed their outer layers into space to create glowing clouds of gas called planetary nebulae. This ejection of mass is uneven, and planetary nebulae can have very complex shapes. NGC 6818 shows knotty filament-like structures and distinct layers of material, with a bright and enclosed central bubble surrounded by a larger, more diffuse cloud. Scientists believe that the stellar wind from the central star propels the outflowing material, sculpting the elongated shape of NGC 6818. As this fast wind smashes through the slower-moving cloud it creates particularly bright blowouts at the bubble’s outer layers. Hubble previously imaged this nebula back in 1997 with its Wide Field Planetary Camera 2, using a mix of filters that highlighted emission from ionised oxygen and hydrogen (opo9811h). This image, while from the same camera, uses different filters to reveal a different view of the nebula. A version of the image was submitted to the Hubble’s Hidden Treasures image processing competition by contestant Judy Schmidt.

Image source: www.nasa.gov/mission_pages/chandra/news/nasas-chandra-ope...
Original caption: When a star like the Sun runs out of fuel, it expands and its outer layers puff off, and then the core of the star shrinks. This phase is known as a "planetary nebula," and astronomers expect our Sun will experience this in about 5 billion years. This Helix Nebula images contains infrared data from NASA's Spitzer Space Telescope (green and red), optical light from Hubble (orange and blue), ultraviolet from NASA's Galaxy Evolution Explorer (cyan), and Chandra's X-rays (appearing as white) showing the white dwarf star that formed in the center of the nebula. The image is about four light years across.

Edited Hubble Space Telescope image of the planetary nebula IRAS 13208-6020. Color/processing variant.
Original caption: The two billowing structures in this NASA/ESA Hubble Space Telescope image of IRAS 13208-6020 are formed from material that is shed by a central star. This is a relatively short-lived phenomenon that gives astronomers an opportunity to watch the early stages of planetary nebula formation, hence the name protoplanetary, or preplanetary nebula. Planetary nebulae are unrelated to planets and the name arose because of the visual similarity between some planetary nebulae and the small discs of the outer planets in the Solar System when viewed through early telescopes. This object has a very clear bipolar form, with two very similar outflows of material in opposite directions and a dusty ring around the star. Protoplanetary nebulae do not shine, but are illuminated by light from the central star that is reflected back to us. But as the star continues to evolve, it becomes hot enough to emit strong ultraviolet radiation that can ionise the surrounding gas, making it glow as a spectacular planetary nebula. But before the nebula begins to shine, fierce winds of material ejected from the star will continue to shape the surrounding gas into intricate patterns that can only be truly appreciated later once the nebula begins to glow. This picture was created from images taken using the High Resolution Channel of Hubble’s Advanced Camera for Surveys. Images taken through an orange filter (F606W, coloured blue) and a near-infrared filter (F814W, coloured red) have been combined to create this picture. The exposure times were 1130 s and 150 s respectively and the field of view is just 22 x 17 arcseconds.

Edited European Southern Observatory image of the planetary nebula ESO 577-24. Processing variant.
Original caption: The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time — around 10,000 years, a blink of an eye in astronomical terms. ESO’s Very Large Telescope captured this shell of glowing ionised gas — the last breath of the dying star whose simmering remains are visible at the heart of this image. As the gaseous shell of this planetary nebula expands and grows dimmer, it will slowly disappear from sight. This stunning planetary nebula was imaged by one of the VLT’s most versatile instruments, FORS2. The instrument captured the bright, central star, Abell 36, as well as the surrounding planetary nebula. The red and blue portions of this image correspond to optical emission at red and blue wavelengths, respectively. An object much closer to home is also visible in this image — an asteroid wandering across the field of view has left a faint track below and to the left of the central star. And in the far distance behind the nebula a glittering host of background galaxies can be seen.
Ha data of "Thor's Helmet" from last night. I had some declination backlash problems so had to throw out alot of the data I got. This is just 20 x 250". I am planning on getting LRGB data this evening, though its getting pretty far west to get alot of good data, but I still want to try.

After four consecutive nights of imaging into the early hours, it's time for an early night :-) I captured the Medusa Nebula during last nights run. Unfortunately I had to throw away 40 mins of data due to guiding errors, otherwise I would have had over four hours of data ... it is very faint.
The Medusa Nebula is a very old and large planetary nebula in the constellation of Gemini on the Canis Minor border. It also known as Abell 21 and Sharpless 274. As it is so big, its surface brightness is very low, with surface magnitudes of between +15.99 and +25 reported. The Medusa was discovered in 1955, and until the early 1980s it was thought to be a supernova remnant.

Messier 27 (M27), also known as the Dumbbell Nebula, Diabolo Nebula or Apple Core Nebula, is a planetary nebula in Vulpecula. The Dumbbell Nebula is large in size and quite bright, which makes it a popular object among amateur astronomers. It can be seen in binoculars and small telescopes.
The nebula covers an area of 8 by 5.6 arc minutes of the apparent sky and has a linear radius of 1.44 light years. Its faint halo stretches out to more than 15 arc minutes. M27 lies at an approximate distance of 1,360 light years, or 417 parsecs, from Earth and has an apparent magnitude of 7.5. It has the designation NGC 6853 in the New General Catalogue.
Messier 27 is the second brightest planetary nebula in the sky, second only to the Helix Nebula in Aquarius, and probably the easiest one to observe because it has a higher surface brightness than the Helix and is therefore easier to find. EAA image.
