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.

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.

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.

English:
M27 (NGC 6853), also known as the Dumbbell Nebula, is a planetary nebula located in the constellation Vulpecula.
It lies around 1,200 light years away and represents the expelled outer layers of a Sun-like star at the end of its life cycle.
Its distinctive shape and colorful gas structures make M27 one of the most observed planetary nebulae in the night sky.

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.

Edited Hubble Space Telescope montage of the same nebula seen twenty years apart, showing significant changes over the period.
Original caption: Archival data from the NASA/ESA Hubble Space Telescope reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades. Witnessing such a swift rate of change in a planetary nebula is exceedingly rare, say researchers. These images captured by Hubble in 1996 (left), when compared to Hubble images taken in 2016 (right), show a nebula that has drastically dimmed in brightness and changed shape. Bright blue shells of gas near the centre of the nebula have all but disappeared, and the wavy edges that earned this nebula its aquatic-themed name are virtually gone. The young nebula no longer pops against the black velvet background of the distant Universe.

M27, the Dumbell Nebula, is a planetary nebula just north of the bright star Altair. A planetary nebula is formed when a star like our Sun generates more outward pressure in its core than its gravity can contain.

Don't know what i was thinking, but i wanted to challenge myself. In retrospect that was stupid!
I recently bought a used VMC95L with the goal of using it for guide scope. Well since the auto-guider has still !!! not arrived, i decided to see what this thing could do.
Well as you can imagine, f/11 is pretty dark, for even the brightest DSO. It's pretty much useful for only moon/planetary work.
My polar alignment was not so great, the scope looks to be out of alignment too, and also my 12v battery pack was dying. All in all a pretty lazy effort. But this was nothing serious.

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.

This image of the "unusual" (not at all!) planetary nebula was obtained using ESO’s Very Large Telescope at the Paranal Observatory in Chile. In the heart of this colourful nebula we can recognize the typical PINCH - creating a discharge pattern that is misinterpreted as a dance of two white dwarfs "orbiting" each other.

Very difficult object to image. I wasn't planning on imaging it but rather the Globular Cluster itself. When I returned home from Africa, Rich Jakiel was looking at the image and suggested we get a detailed finder chart of the PN just in case it was there. We secured a finder chart, very detailed, from Hubble images. The article mentions the red star and the blue star above and below the PN. The PN itself is the light blue spot between the two stars.

Edited Hubble Space Telescope image of the planetary nebula NGC 6210, not looking very symmetrical.
Original caption: The NASA/ESA Hubble Space Telescope has taken a striking high resolution image of the curious planetary nebula NGC 6210. Located about 6500 light-years away, in the constellation of Hercules, NGC 6210 was discovered in 1825 by the German astronomer Friedrich Georg Wilhelm Struve. Although in a small telescope it appears only as a tiny disc, it is fairly bright. NGC 6210 is the last gasp of a star slightly less massive than our Sun at the final stage of its life cycle. The multiple shells of material ejected by the dying star form a superposition of structures with different degrees of symmetry, giving NGC 6210 its odd shape. This sharp image shows the inner region of this planetary nebula in unprecedented detail, where the central star is surrounded by a thin, bluish bubble that reveals a delicate filamentary structure. This bubble is superposed onto an asymmetric, reddish gas formation where holes, filaments and pillars are clearly visible. The life of a star ends when the fuel available to its thermonuclear engine runs out. The estimated lifetime for a Sun-like star is some ten billion years. When the star is about to expire, it becomes unstable and ejects its outer layers, forming a planetary nebula and leaving behind a tiny, but very hot, remnant, known as white dwarf. This compact object, here visible at the centre of the image, cools down and fades very slowly. Stellar evolution theory predicts that our Sun will experience the same fate as NGC 6210 in about five billion years. This picture was created from images taken with Hubble’s Wide Field Planetary Camera 2 through three filters: the broadband filter F555W (yellow) and the narrowband filters F656N (ionised hydrogen), F658N (ionised nitrogen) and F502N (ionised oxygen). The exposure times were 80 s, 140 s, 800 s and 700 s respectively and the field of view is only about 28 arcseconds across.
M27 was the first Planetary Nebula ever discovered, in 1764 by Charles Messier. It is estimated to be ~10,000 years old based on its rate of expansion from the central White Dwarf remnant.
