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.
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.
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.
Der Ringnebel ist ein planetarischer Nebel, also der Überrest eines vergangenen Sterns mit dem Weißen Zwerg im Zentrum. Der Nebel trägt die fachliche Bezeichnung Messier 57 (M57), bzw NGC 6720, und befindet sich im Sommersternbild Leier. Das ist nahe der Sommermilchstrasse und des Sternbildes Schwan.
Das gleiche Bild habe ich noch einmal in Graustufen umgewandelt und anschließend invertiert, um schwächere Strukturen sichtbar zu machen. Das Bild findet sich einen Klick nebenan.
Aufgenommen am 20.05.2020 mit der modifizierten Canon EOS 7Da und dem Meade LX50 10-Zoll Spiegelteleskop auf einer Skywatcher EQ6-R-Pro Montierung. Die Brennweite betrug F10 / 2540mm. Belichtung mit 40 Einzelbildern zu je 150 Sekunden (= 100 Minuten Gesamtbelichtungszeit) bei ISO 1600. Das Guiding erfolgte mit einer ZWO ASI mono am Skywatcher ED 80/600mm Refraktor per PHD2.
Edited Hubble Space Telescope image of the planetary nebula NGC 2022. Inverted grayscale 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 in Ursa Major. Taken using a 300mm f/4 Newtonian telescope with an Atik 16IC-S camera. 11x120s exposures using a CLS filter. Captured, stacked and processed in Nebulosity 3. Darks and flats applied.
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.

This image is 26 images stacked at 1 minute exposures and ISO 1600, with 10 dark frames. I was going to crop this image down, but the star field really adds to the image. The majority of this nebula came out a turquoise color, while the two ends have a red coloring to them.

Edited European Southern Observatory image of the planetary nebula Hen 2-248.
Original caption: This image of the unusual planetary nebula was obtained using ESOâs Very Large Telescope at the Paranal Observatory in Chile. In the heart of this colourful nebula lies a unique object consisting of two white dwarf stars, each with a mass a little less than that of the Sun. These stars are expected to slowly draw closer to each other and merge in around 700 million years. This event will create a dazzling supernova of Type Ia and destroy both stars.

A planetary nebula, this white dwarf star begins its life by casting off the cocoon that enclosed its former self. It contains one of the hottest white dwarf stars known. White dwarf can be seen as the bright dot near the center. Our Sun will become a "white dwarf butterfly"--in another five billion + years.
Watercolor and gouache painting on rice paper.This mysterious shape reminded me of many verses from the Psalms in the Bible of acknowledging and praising God. Psalm 89:5, 6 says: "The heavens praise your wonders, O Lord, your faithfulness too, in the assembly of the holy ones. For who in the skies above can compare with the Lord? Who is like the Lord among the heavenly beings?"

Der Hantelnebel ist ein planetarischer Nebel, also der Überrest eines vergangenen Sterns mit dem Weißen Zwerg im Zentrum. Der Nebel heisst so, weil die hellsten Bereiche visuell im Teleskop so ähnlich aussehen wie eine Hantel. Auf dieser Langbelichtung ist die Hantelform bereits nicht mehr zu erkennen.
Der Nebel trägt die fachliche Bezeichnung Messier 27 (M27), bzw NGC 6853, und befindet sich im Sternbild Fuchs. Das ist mitten in der Sommermilchstrasse nahe des Sternbildes Schwan.
Aufgenommen am 23.08.2019 mit der Canon EOS 7D Mark II und dem Meade LX50 10-Zoll Spiegelteleskop auf einer Skywatcher EQ6-R-Pro Montierung. Die Brennweite betrug F6,3 / 1800mm. Belichtung mit 57 Einzelbildern zu je 80 Sekunden (= 76 Minuten Gesamtbelichtungszeit) bei ISO 1250.

M57, the aptly named "Ring nebula". This is a planetary nebula, which is to say that it is a dying star that is emitting various gases which generate all the colors. I looked for this a few times before when it was low in the sky but never saw it. This morning (early this morning!!!) it was high in the sky and easy to find. This was shot with the camera using the telescope as the lens. There are some tracking errors that I hope to iron out next time with PEC (and a little TLC!).
New (today) Hubble Space Telescope image of the Ring Nebula, showing a lot of detail not normally seen.

Edited Hubble Space Telescope image of the planetary nebula NGC 1501.
Original caption: This new image from Hubble’s Wide Field Planetary Camera 2 showcases NGC 1501, a complex planetary nebula located in the large but faint constellation of Camelopardalis (The Giraffe). Discovered by William Herschel in 1787, NGC 1501 is a planetary nebula that is just under 5000 light-years away from us. Astronomers have modelled the three-dimensional structure of the nebula, finding it to be a cloud shaped as an irregular ellipsoid filled with bumpy and bubbly regions. It has a bright central star that can be seen easily in this image, shining brightly from within the nebula’s cloud. This bright pearl embedded within its glowing shell inspired the nebula’s popular nickname: the Oyster Nebula. While NGC 1501's central star blasted off its outer shell long ago, it still remains very hot and luminous, although it is quite tricky for observers to spot through modest telescopes. This star has actually been the subject of many studies by astronomers due to one very unusual feature: it seems to be pulsating, varying quite significantly in brightness over a typical timescale of just half an hour. While variable stars are not unusual, it is uncommon to find one at the heart of a planetary nebula. It is important to note that the colours in this image are arbitrary. A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Marc Canale. Links Marc Canale on Flickr
