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.

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.

Compared to Minkowski 1-63, this planetary nebula isn't much to look at, but it is still a wonderful planetary nebula. As with M1-63, The data for Perek 2-7 is probably good enough to make a color image, but for now, I'm going to avoid embarrassing myself. This image was taken by the WFC3 instrument on the Hubble Space Telescope and is part of proposal 11657.

Here is another planetary nebula, greyscale this time, that I got from a DADS request. Processing this in FITS Liberator was very confusing for me because all of the widefield data showed up as a featureless grey rectangle. I am new to this. I realized I could change it to Log(Log(x)) and see some faint stars. I'd then autoscale it until It looked clear enough. I've never done it that way before and hope I'll remember. You could probably get a decent color image out of the data, but my skills in processing with color are quite lacking (which is why I have not been processing many color datasets).
The image is at original size. It was taken by the WFC3 instrument on the Hubble Space Telescope. It is part of proposal 11657. I stacked narrow and wide field images to get this.

Edited Hubble Space Telescope image of the Bubble Nebula (NGC 7635) released on Hubble's 26th birthday.
Original caption: Twenty-six candles grace NASA's Hubble Space Telescope's birthday cake this year, and now one giant space "balloon" will add to the festivities. Just in time for the 26th anniversary of Hubble's launch on April 24, 1990, the telescope has photographed an enormous, balloon-like bubble being blown into space by a super-hot, massive star. Astronomers trained the iconic telescope on this colorful feature, called the Bubble Nebula, or NGC 7635. The bubble is 7 light-years across — about one-and-a-half times the distance from our sun to its nearest stellar neighbor, Alpha Centauri. The Bubble Nebula lies 7,100 light-years from Earth in the constellation Cassiopeia.

The Ring Nebula is a planetary nebula (which can be misleading because they have nothing to do with planets). A planetary nebula is an expanding shell of glowing gas that was thrown out into space by a dying star. The Ring nebula is about 2000 light years away.
This image was taken using a 6" telescope at the St. George campus of the University of Toronto.
I pulled the IR filter out of my Canon 450D last week and last night was the first test of the 'new' camera.
top image is pre mod, bottom is post mod. I did not install a UV/IR cut filter in the camera which is not supposed to work well for any optical system that contains refracting elements. The EdgeHD series scopes do contain a field flattener in the tube so I wasn't sure what to expect. So far, so good by the looks of things. Stars are nice and tight and color balnce is good, with a hint of the faint red outer shell showing around the nebula. Star colours are a bit weaker though, and I might have to try some in camera white balance adjustments for the next shot.

Shot through my 10" Meade LX200 telescope, the "eyes" of the Owl Nebula are just visible in this 50-second time exposure.
Taken at the 2009 Winter Star Party in the Florida Keys.
From the Wikipedia entry:
The Owl Nebula (also known as Messier Object 97 or NGC 3587) is a planetary nebula in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781.
M97 is regarded as one of the more complex of the planetaries. The 16th magnitude central star has about 0.7 solar mass and the nebula itself about 0.15 solar mass. The nebula formed roughly 6,000 years ago.
The nebula gets it name due to the appearance of owl-like "eyes" when view through a large (>200 mm) telescope under dark sky conditions with the aid of a so-called "nebula filter." The "eyes" are also easily visible through photographs taken of the nebula.
_ND35914
M97 is a planetary nebula. It is what remains shortly (10 to 50 thousand years) after a star the size of our sun reaches the end of its life. A white dwarf star resides at the center of planetary nebulae -- an object so dense that a teaspoon would have as much mass as a fully loaded 18-wheeler. 13 minute total exposure taken with an Atik 314L+ CCD camera on a Celestron 9.25" Edge HD at f/6.3 on a CGEM mount. Guiding done by PHD. Processing done using Deep Sky Stacker and Photoshop Elements.

Edited Hubble Space Telescope image of the planetary nebula NGC 2022. Color/processing variant.
Original caption: Although it looks more like an entity seen through a microscope than a telescope, this rounded object, named NGC 2022, is certainly no alga or tiny, blobby jellyfish. Instead, it is a vast orb of gas in space, cast off by an ageing star. The star is visible in the orb's centre, shining through the gases it formerly held onto for most of its stellar life. When stars like the Sun grow advanced in age, they expand and glow red. These so-called red giants then begin to lose their outer layers of material into space. More than half of such a star's mass can be shed in this manner, forming a shell of surrounding gas. At the same time, the star's core shrinks and grows hotter, emitting ultraviolet light that causes the expelled gases to glow. This type of object is called, somewhat confusingly, a planetary nebula, though it has nothing to do with planets. The name derives from the rounded, planet-like appearance of these objects in early telescopes. NGC 2022 is located in the constellation of Orion (The Hunter).

Edited Spitzer Space Telescope image of the Helix Nebula. Inverted grayscale variant.
Original caption: A newly expanded image of the Helix nebula lends a festive touch to the fourth anniversary of the launch of NASA's Spitzer Space Telescope. This spectacular object, a dying star unraveling into space, is a favorite of amateur and professional astronomers alike. Spitzer has mapped the expansive outer structure of the six-light-year-wide nebula, and probed the inner region around the central dead star to reveal what appears to be a planetary system that survived the star's chaotic death throes.
Edited Hubble Space Telescope image of the planetary nebula IRAS 13208-6020.
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.
Reading up on M22, I discovered that it contains a planetary nebula, GJJC1. So I looked at my M22 capture to see if I could see it.
This is the inverted luminance image. After inspecting other images I think this is PN GJJC1.
As you can see, the guiding was not perfect.

Kaleidoscopic version of a Hubble Space Telescope image of a planetary nebula.
Original caption: It may look like something from The Lord of the Rings, but this fiery swirl is actually a planetary nebula known as ESO 456-67. Set against a backdrop of bright stars, the rust-coloured object lies in the constellation of Sagittarius (The Archer), in the southern sky. Despite the name, these ethereal objects have nothing at all to do with planets; this misnomer came about over a century ago, when the first astronomers to observe them only had small, poor-quality telescopes. Through these, the nebulae looked small, compact, and planet-like — and so were labelled as such. When a star like the Sun approaches the end of its life, it flings material out into space. Planetary nebulae are the intricate, glowing shells of dust and gas pushed outwards from such a star. At their centres lie the remnants of the original stars themselves — small, dense white dwarf stars. In this image of ESO 456-67, it is possible to see the various layers of material expelled by the central star. Each appears in a different hue — red, orange, yellow, and green-tinted bands of gas are visible, with clear patches of space at the heart of the nebula. It is not fully understood how planetary nebulae form such a wide variety of shapes and structures; some appear to be spherical, some elliptical, others shoot material in waves from their polar regions, some look like hourglasses or figures of eight, and others resemble large, messy stellar explosions — to name but a few. A version of this image was entered into the Hubble's Hidden Treasures image processing competition by contestant Jean-Christophe Lambry
Edited European Southern Observatory image of the planetary nebula ESO 577-24. Color/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.
