The Ring Nebula (also known as the Messier 57) is located in the constellation Lyra. It is a planetary nebula 2300 light years away. This image was taken by Doug Spalding from my back porch in Overland Park, KS. Equipment used was a CGE1100 telescope at F/10 with an Orion DSCI II imager. 10 images X 60sec each. Stacked with Maxim DL essentials.
Photographed prime-focus with a Meade LX-5/2080 using no focal reducers/filters, and only a T-ring adapter and adapter tube assembly.
Another rough shot on the night I got my telescope back from repairs.
13x 30 second exposures, 6.5 minutes total exposure time. ... Obviously could have centered it better to avoid the field curvature.
M57 is a planetary nebula ... a shell of gass puffed off of a star similar to our star but near the end of it's life. A last hoorah before fading out as a white dwarf.
One of my favorite objects... As a teenager I could see this little smoke puff from light-polluted skies with my 4.5" Tasco, and it was easy to find to boot. I think the Tasco had a 10 mm finderscope... it was easier to sight along the tube than use the finderscope.
Anyway, this image was constructed from a stack of 29 15-second photos. This is the first time I tried to image M57 and I was very surprised to see its bright blue colour on a single 15" exposure.
The NASA/ESA Hubble Space Telescope has captured the sharpest view yet of the most famous of all planetary nebulae: the Ring Nebula (M57). In this October 1998 image, the telescope has looked down a barrel of gas cast off by a dying star thousands of years ago. This photo reveals elongated dark clumps of material embedded in the gas at the edge of the nebula; the dying central star floating in a blue haze of hot gas. The nebula is about a light-year in diameter and is located some 2, 000 light-years from Earth in the direction of the constellation Lyra.

The previous M57 photo, upsampled 3x. Blown up to show the central star within the planetary nebula
Stars are squiggly from a poorly aligned telescope mount, and from the target being too far from the center of the image.
The Ring Nebula (also catalogued as Messier 57, M57 or NGC 6720) is a planetary nebula 2,300 light-years from Earth and is found in the northern constellation of Lyra. Such objects are formed when a shell of ionized gas is expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf.
This cropped image is part of a series of experiments in using a guided telescope in order to achieve longer exposures and lower ISOs.

This new image shows the dramatic shape and colour of the Ring Nebula, otherwise known as Messier 57. From Earth’s perspective, the nebula looks like a simple elliptical shape with a shaggy boundary. However, new observations combining existing ground-based data with new NASA/ESA Hubble Space Telescope data show that the nebula is shaped like a distorted doughnut. This doughnut has a rugby-ball-shaped region of lower-density material slotted into in its central “gap”, stretching towards and away from us.

Narrowband SII-Ha-OIII with 4x5min subs, no flats, no bias.
The first almost dark night since early April was lit up with a full moon and occasional Perseids. The mount head attachment to the pier was altered (still not perfect) and a good deal of the short darkness was spent polar aligning the mount. After reaching a reasonable accuracy I still had about an hour of tolerable darkness for narrowband work, so M57 was chosen as the start of season target.
I generated this image from Hubble data at the HLA and at three filter wavelengths of F469, F502 and F658. I used F658 for the red channel as this seems to be the rendition used in the NASA/STScl/AURA version of the image up on Wiki
I have more images on my website here
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.

NASA's Spitzer Space Telescope finds a delicate flower in the Ring Nebula, as shown in this image. The outer shell of this planetary nebula looks surprisingly similar to the delicate petals of a camellia blossom. A planetary nebula is a shell of material ejected from a dying star. Located about 2,000 light years from Earth in the constellation Lyra, the Ring Nebula is also known as Messier Object 57 and NGC 6720. It is one of the best examples of a planetary nebula and a favorite target of amateur astronomers.
The "ring" is a thick cylinder of glowing gas and dust around the doomed star. As the star begins to run out of fuel, its core becomes smaller and hotter, boiling off its outer layers.
The telescope's infrared array camera detected this material expelled from the withering star. Previous images of the Ring Nebula taken by visible-light telescopes usually showed just the inner glowing loop of gas around the star. The outer regions are especially prominent in this new image because Spitzer sees the infrared light from hydrogen molecules. The molecules emit infrared light because they have absorbed ultraviolet radiation from the star or have been heated by the wind from the star.
Un nouveau traitement pour les mêmes prises que la précédente photo de M57, juste pour voir jusqu'où je peux pousser (à noter qu'ici je ne coupe pas l'étoile brillante en haut à gauche...)
... et aussi pour voir ce qu'en dit le bot astrometry.

This image is a composite of the Ring Nebula (Messier 57). This combines new Hubble Wide Field Camera 3 data with observations of the nebula’s outer halo from the Large Binocular Telescope (LBT) in Arizona, USA. In this image, the knotty, turbulent space around the nebula shows up dramatically, creating an almost psychedelic effect. The Large Binocular Telescope is part of the Mount Graham International Observatory in Arizona.

This is the first image I stacked various calibration frames with, including flats. It took a long time, but it was worth it.

La nébuleuse planétaire de la Lyre (M57). C'est ce qu'il reste d'une étoile un peu plus massive que le Soleil après sa mort : dans cinq milliards d'années, notre Soleil deviendra une étoile géante rouge quand il aura fusionné tout son hydrogène en hélium, et commencera à fusionner son hélium tout en éjectant de la matière en quantités de plus en plus grandes. Plus tard ce qu'il restera de cette matière éjectée sera un grand nuage de gaz qui ressemblera à cette belle nébuleuse... La couleur rouge, au bord, signale la présence d'hydrogène ; la couleur bleu-vert au centre signale la présence d'oxygène, un élément plus massif fabriqué par ces vieilles étoiles. Photo prise avec une caméra GC-Cam au foyer d'un télescope Skywatcher 150/750 et d'une lentille de Barlow x2. Photo fortement retraitée avec GIMP pour retirer le bruit de fond. Par contre, je n'ai pas touché à la répartition des couleurs, juste augmenté le contraste et la luminosité !

La nébuleuse planétaire de la Lyre (Messier 57) est le reste d'une étoile comparable au Soleil qui a lentement rejeté son enveloppe externe de gaz loin dans l'espace après avoir fini sa vie d'étoile. Image réalisée avec une caméra Altaïr GP-Cam montée sur un Barlow x 2 au foyer d'un télescope Skywatcher 150/750. Les images, peu nettes en raison probablement de la turbulence, étaient pauvres en étoiles ce qui m'a empêché d'empiler ces 42 clichés automatiquement avec un logiciel adapté, c'est pourquoi je les ai alignées à la main avec GIMP.
