edit 12/8: I uploaded a new version without the sii channel to make the nebula look a bit more natural. it is no longer green.
this is a pretty planetary nebula, observed by ESO's New Technology Telescope. the nebula appears very green because ha is mapped to green while the sii is mapped to red, this nebula not having very strong sii emissions. I debated whether or not to include that data, but I think it's good to have. there's also some newer VLT data available for this object, but the exposures were much shorter and the chip gap ran through the nebula.

Edited Hubble Space Telescope image of the planetary nebula NGC 6565.
Original caption: A dying star’s final moments are captured in this image from the NASA/ESA Hubble Space Telescope. The death throes of this star may only last mere moments on a cosmological timescale, but this star’s demise is still quite lengthy by our standards, lasting tens of thousands of years! The star’s agony has culminated in a wonderful planetary nebula known as NGC 6565, a cloud of gas that was ejected from the star after strong stellar winds pushed the star’s outer layers away into space. Once enough material was ejected, the star’s luminous core was exposed and it began to produce ultraviolet radiation, exciting the surrounding gas to varying degrees and causing it to radiate in an attractive array of colours. These same colours can be seen in the famous and impressive Ring Nebula (heic1310), a prominent example of a nebula like this one. Planetary nebulae are illuminated for around 10 000 years before the central star begins to cool and shrink to become a white dwarf. When this happens, the star’s light drastically diminishes and ceases to excite the surrounding gas, so the nebula fades from view. A version of this image was entered into the Hubble’s Hidden Treasures basic image competition by contestant Matej Novak.

The image in the middle is one I created using x-ray, optical, and radio images (which came out far too green), and the one on the right is the delta between the first two.
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).

A planetary nebula is 2300 light-years from Earth and is actually a barrel-shaped cloud of gas shrugged off by a dying central star. Its natural appearing colors indicate temperature: hot blue gas near the energizing central star gives way to progressively cooler green and yellow, and the coolest red gas along the outer boundary.
Watercolor and gouache painting on rice paper. I love the primary rings of colors. The Bible verse from Habakkuk 3:3-4 says, "His glory covered the heavens, and the earth was full of His praise. His brightness was like the sunrise. He had rays flashing from His hand, and there His power was hidden."

Edited European Southern Observatory image of planetary nebula Fleming 1.
Original caption: This new ESO Very Large Telescope image shows the planetary nebula Fleming 1 in the constellation of Centaurus (The Centaur). This striking object is a glowing cloud of gas around a dying star. New observations have shown that it is likely that a very rare pair of white dwarf stars lies at the heart of this object. Their orbital motions can fully explain the remarkably symmetric structures of the jets in the surrounding gas clouds in this and similar objects.
This young planetary nebula is about 8,000 light-years away from Earth and consists of delicate rings of colorful gas. The central star's life is running out of time. Closing phases of life occur as the outer layers are ejected, it's core becoming a cooling, fading white dwarf.
This eerie image keeps you coming back into its gaze. My mind keeps repeating the verse about how God's eyes run to and fro throughout the whole earth, to show Himself strong on behalf of those whose heart is loyal to Him (2 Chronicles 16:9).
Edited European Southern Observatory image of the Helix Nebula. Inverted grayscale 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.

Dans la constellation des Gémeaux (Gemini), à 4 300 a.l. de la Terre, la nébuleuse planétaire NGC 2371 comprend en son centre le noyau super-chaud d'une ancienne géante rouge, maintenant dépouillée de ses couches externes, avec des nuages roses proéminents. Les nombreux points roses très petits marquent des nœuds de gaz relativement denses et petits, se trouvant sur les côtés diamétralement opposés de l’astre. Ces caractéristiques semblent représenter l’éjection de gaz de l’étoile le long d’une direction spécifique, celle du jet ayant probablement changé au cours des derniers milliers d’années. La raison de ce comportement n’est pas bien comprise, mais pourrait être liée à la présence possible d’une deuxième étoile en orbite autour de l’étoile centrale. Dans quelques milliers d’années, la nébuleuse se dissipera dans l’espace, l’étoile centrale se refroidissant progressivement, pour devenir finalement une naine blanche. L’image Hubble en fausse couleur est réalisée à partir d’expositions prises à travers des filtres qui détectent la lumière du soufre et de l’azote en rouge, de l'hydrogène en vert et de l'oxygène en bleu (cf. site Hubble).

a modest planetary nebula.
since the nebulosity of these eso planetaries so far really only shows up in one or two channels, the colours are pretty weird, so I did some somewhat weird processing too. I set a pseudogreen version to colour at 30% opacity in order to subdue the colours a little.

Another planetary nebula. This one supposedly looks like an eskimo with a big fluffy parka on. Hmmm. Maybe with better resolution. Anyway last night was the first clear night in a long time with decent visability. For the plains just East of the Rockies that means good clarity but poor turbulence. So this is probably about as good as I can get these tiny planetaries from out here. I can't wait to haul the telescope down to Arizona or New Mexico sometime this Summer for smoother skies!

Not sure why,but I only posted an Ha version;

Edited Spitzer Space Telescope image of the Helix Nebula. Color/processing variant.
Original caption: A dying star is throwing a cosmic tantrum in this combined image from NASA's Spitzer Space Telescope and the Galaxy Evolution Explorer (GALEX), which NASA has lent to the California Institute of Technology in Pasadena. In death, the star's dusty outer layers are unraveling into space, glowing from the intense ultraviolet radiation being pumped out by the hot stellar core.
This object, called the Helix nebula, lies 650 light-years away, in the constellation of Aquarius. Also known by the catalog number NGC 7293, it is a typical example of a class of objects called planetary nebulae. Discovered in the 18th century, these cosmic works of art were erroneously named for their resemblance to gas-giant planets.
Planetary nebulae are actually the remains of stars that once looked a lot like our sun. These stars spend most of their lives turning hydrogen into helium in massive runaway nuclear fusion reactions in their cores. In fact, this process of fusion provides all the light and heat that we get from our sun. Our sun will blossom into a planetary nebula when it dies in about five billion years.
When the hydrogen fuel for the fusion reaction runs out, the star turns to helium for a fuel source, burning it into an even heavier mix of carbon, nitrogen and oxygen. Eventually, the helium will also be exhausted, and the star dies, puffing off its outer gaseous layers and leaving behind the tiny, hot, dense core, called a white dwarf. The white dwarf is about the size of Earth, but has a mass very close to that of the original star; in fact, a teaspoon of a white dwarf would weigh as much as a few elephants!
The glow from planetary nebulae is particularly intriguing as it appears surprisingly similar across a broad swath of the spectrum, from ultraviolet to infrared. The Helix remains recognizable at any of these wavelengths, but the combination shown here highlights some subtle differences.
The intense ultraviolet radiation from the white dwarf heats up the expelled lay

I was surprised to find concentric shells around this one, much like the Cat's Eye Nebula that is so famous. They are quite faint and were difficult to process but they should be easy enough to spot.
Processing notes: I combined the PC data with the rest of the WF data to create a partially more detailed image than without the PC data. The bad part of this is that I have a very hard time getting the two to match up no matter what I do and some parts of the PC data are actually less detailed. I sort of understand why but I don't understand it well enough to explain it better. I mix and matched it in a way I thought was both aesthetic and faithful to the object. Anyway, there are some faint lines visible across the image because of this.

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 Hubble Space Telescope image of the Butterfly Nebula. Color/processing variant.
Original caption: Hubble was recently retrained on NGC 6302, known as the "Butterfly Nebula," to observe it across a more complete spectrum of light, from near-ultraviolet to near-infrared, helping researchers better understand the mechanics at work in its technicolor "wings" of gas. The observations highlight a new pattern of near-infrared emission from singly ionized iron, which traces an S shape from lower left to upper right. This iron emission likely traces the central star system ís most recent ejections of gas, which are moving at much faster speeds than the previously expelled mass.
The star or stars at its center are responsible for the nebula's appearance. In their death throes, they have cast off layers of gas periodically over the past couple thousand years. The "wings" of NGC 6302 are regions of gas heated to more than 36,000 degrees Fahrenheit that are tearing across space at more than 600,000 miles an hour.
NGC 6302 lies between 2,500 and 3,800 light-years away in the constellation Scorpius.
There is very few images of this extremely dim planetary nebula in Pegasus.

This is a fun image. The guide star acquisition had failed, meaning that there was no lock on the target. This meant that there were very few exposures since they were trying to image blindly. This makes for a pretty gross image.
