El resto de supernova de Vela, también llamado Vela XYZ, SNR G263.9-03.3 y AJG 8,1 es un resto de supernova situado en la constelación de Vela. Es uno de los restos de supernovas más estudiados y más cercanos a la Tierra. Aunque se superpone al resto de supernova Puppis A, este último está unas cuatro veces más lejos.
El resto de supernova de Vela está asociado al púlsar de Vela (PSR J0835-4510): la relación entre ambos objetos astronómicos, realizada por astrónomos de la Universidad de Sídney en 1968, fue la prueba directa de que las supernovas dan lugar a estrellas de neutrones. La rotación de este púlsar, cuya frecuencia es de aproximadamente 11,2 Hz, ha sido estudiada exhaustivamente desde su descubrimiento. Fue el primer púlsar en donde se detectó una «falla» o «defecto» en su rotación; cuando se detectó de nuevo, dos años y medio más tarde, quedó claro que dichas «fallas» eran grandes y frecuentes. En estos episodios, la frecuencia de rotación se incrementa en unos 20 μHz. (Wikipedia)

this photo unfortunately reveals some issues with this lens wide open- namely halos around bright stars and lens flare around the brightest star (Mimosa Beta Crux)
Removed as much of the halos as I could in processing but Mimosa is still very apparent, Could have cropped it out I suppose.
Will need to try it closed a couple of stops next time
My latest image from the backyard is the dynamic-looking 'Lion Nebula' in the constellation Cepheus. (I love the colors in this one)
This image includes exactly 7 hours of total exposure time (84 x 300s) using the little RedCat 51 telescope with a color camera and light pollution filter attached.
The Optolong L-eXtreme filter has officially become my most used filter of all time - and it consistently provides me with useful data from my Bortle 6 backyard.
Dual-narrowband filters have really made astrophotography from the city a lot more obtainable.

This image, shot during May to July 2024, shows a heavily crowded are in constellation Cepheus, with a blend of several nebula types. In the center, pillars of dust create a wormlike structure called LDN 1217, which ends in a bluish reflexion nebula (VdB 152). In the background, more dark nebulas can be seen, in some parts being lit by hot blue giants stars. In this area, it partially blocks the red light coming from the Ha strands farther away, which impairs the sense of perspective.
This is my longest project so far (61h29) and one of the hardest. Why? Not because of technical issues but in striking a balance between all these nebulas in a way that any of them overwhelms the others and thus show the richness of this area.
Have I achieved it? Perhaps yes, to my eye. Or maybe not… But the important is that I am quite happy with it.

IC 434 is an emission nebula visible in the constellation of Orion; thanks to its presence it is possible to observe the famous Horsehead Nebula, a dark cloud that overlaps it on our line of sight.
This is an H II region that extends south of Alnitak, on the southwestern edge of the large Orion B cloud; it has a very elongated shape in a north-south direction and receives the ionizing wind directly from the star σ Orionis, a bright member of the large Orion OB1 association.
The nebula reaches 70' in length and is easily shown in long exposure photos or CCD images, although its thickness is only a few arc minutes.
The temperature of the region was measured using various methodologies and exploiting various radiation ratios, initially obtaining values between 8000 K and 7600 K;
subsequently this value was reduced to 3360 K and even less depending on the map taken as reference.[3] A study on electronic temperature conducted in 1992 instead provided a value more similar to the previous ones, which is around 6000 K.

A l'occasion d'un passage dans la famille dans le sud, j'ai profité de 3 nuits très claires dans le sud de la France pour me faire un bivouac astro en haut du Gros Cerveau au dessus de Sanary sur Mer et imager la nébuleuse de la trompe d'éléphant que je n'avais jamais faite. Cette nébuleuse se trouve dans la constellation de Cephée, bien observable (en astrophotographie seulement) dans le ciel d'été car montant dans le ciel en début de nuit. J'ai fait 2 sessions en RVB et une en HOO (filtre optolong L-Enhance). La photo présentée ici est une photo cumulant 14h38 d'exposition. Les détails concernant la photographie sont donnés plus bas (EXIFs).
Anecdote : le seul soir où je n'y suis pas allé, le vendredi 10/05/24, soirée à rallonge que j'ai passé avec des amis, c'est le seul soir où il y a eu d'importantes aurores boréales ... que je n'ai donc pas vues ! Le lendemain soir (le samedi 11/05) quand je suis retourné en haut de la montagne déserte l'avant veille, les gens se pressaient pour aller observer les aurores boréales qui ... n'ont pas montré le bout de leur nez cette nuit là. Mais plusieurs en ont profité pour passer une soirée avec moi qui ai pris plaisir à faire les présentations avec les nébuleuses et autres amas visibles ce soir là en leur permettant de belles observations avec mes jumelles.
* Description de la photo :
Sur la photo apparaissent 2 grandes nébuleuses lumineuses et des nébuleuses sombres. L'astrométrie donnée ici (nova.astrometry.net/annotated_full/10666855) répertorie d'autres objets d'intérêt.
- IC 1396 (Nébuleuse de la trompe d'éléphant). C'est la grande nébuleuse sur la droite de la photo. IC 1396 qui ressemble un peu à la nébuleuse de la rosette contient également un amas en son centre. C'est une nébuleuse en émission située à environ 2400 années lumières (AL) de nous. Elle porte son nom à cause d'une nébuleuse sombre bien visible à droite de son centre sur la photo, nébuleuse sombre qui comporte un globule nébuleux en son centre, lieu d'acite formation d'étoiles. L'étoile très visible en haut de la nébuleuse et qui éclaire celle-ci est nommée Etoile Grenat ou Erakis ; il s'agit de mu-Cephei. C'est une étoile variable pulsante dans un système double.
- SH 2-132 / LBN 473 (Nébuleuse du lion) et LDN 1150 et 1154. Cette nébuleuse est produite par l'ionisation de gaz par 2 étoiles très chaudes, étoiles de Wolf-Rayet HD 211564 et HD 211853. elle est distante de 10400 années lumières donc bien plus loin qu'IC 1396. A la droite de la nébuleuse, on voit 2 zones plus foncées. Il s'agit de LDN 1150 et LDN 1154, 2 nébuleuses obscures (des nuages de poussières interstellaires).
- zeta-Cephei, LBN 479 et LBN 474. En haut de la photo, il y a une étoile très brillante entourée à gauche et à droite de 2 nébuleuses de faible intensité. L'étoile est zeta-Cephei, une supergéante rouge dans un système binaire à eclipses située à 840 AL de nous. A gauche se trouve LBN 479 et à droite LBN 474, 2 nuages d'hydrogène éclairé et ionisé par zeta-Cephei.
- B174 / LDN 1165. A droite de zeta-cephei, au dessus d'IC 1396, on observe une grande région marbrée de nébuleuses obscures. Je ne vais pas donner tous leurs noms. La plus grande est B174.
- Kruger 60. L'objet répertorié sous ce nom dans l'astrométerie (voie le lien plus haut) est une étoile double de magnitude 9.8. Il s'agit d'un couple d'étoiles naines rouges très proches puisqu'elles sont distantes en moyenne de 9.5 unités astronomiques (9.5 x 150 millions de km), soit la distance Soleil-Saturne, distance variant de 5.5 UA à 13.5 UA.
- IC 1442, NGC 7245, NGC 7226, NGC 7175, NGC 7234, NGC 7261, NGC 7281. Tous ces objets sont des amas ouverts.

During a visit to my family in the south, I took advantage of three very clear nights in the south of France to set up an astro-bivouac on top of Gros Cerveau above Sanary-sur-Mer and image the Elephant Trunk Nebula, which I had never photographed before. This nebula is located in the constellation Cepheus, and is well observable (in astrophotography only) in the summer sky as it rises early in the night. I had two RGB sessions and one HOO session (with an Optolong L-Enhance filter). The photo presented here is a compilation of 14 hours and 38 minutes of exposure. The details regarding the photograph are provided below (EXIFs).
Anecdote: The only evening I didn’t go up, Friday, May 10, 2024, I spent a long evening with friends. It was the only night with significant auroras... which I did not see! The next evening (Saturday, May 11) when I returned to the deserted mountain top from the previous night, people were rushing to observe the auroras which... did not show up that night. But several people took the opportunity to spend an evening with me, and I enjoyed introducing them to the nebulae and other clusters visible that night, allowing them to make some beautiful observations with my binoculars.
* Description of the photo:
In the photo, two large luminous nebulae and dark nebulae are visible. The astrometry provided here (nova.astrometry.net/annotated_full/10666855) lists other objects of interest.
- IC 1396 (Elephant Trunk Nebula): This is the large nebula on the right side of the photo. IC 1396, which resembles the Rosette Nebula, also contains a cluster at its center. It is an emission nebula located about 2400 light-years (LY) away. It is named after a dark nebula, clearly visible to the right of its center in the photo, which contains a nebular globule, an active star formation region. The very visible star at the top of the nebula that illuminates it is named the Garnet Star or Erakis; it is mu-Cephei, a pulsating variable star in a double system.
- SH 2-132 / LBN 473 (Lion Nebula) and LDN 1150 and 1154: This nebula is produced by the ionization of gas by two very hot stars, Wolf-Rayet stars HD 211564 and HD 211853. It is located 10,400 light-years away, much farther than IC 1396. To the right of the nebula, two darker regions are visible. These are LDN 1150 and LDN 1154, two dark nebulae (clouds of interstellar dust).
- Zeta-Cephei, LBN 479, and LBN 474: At the top of the photo, there is a very bright star surrounded on the left and right by two faint nebulae. The star is Zeta-Cephei, a red supergiant in an eclipsing binary system located 840 LY away. To the left is LBN 479 and to the right is LBN 474, two clouds of ionized hydrogen lit by Zeta-Cephei.
- B174 / LDN 1165: To the right of Zeta-Cephei, above IC 1396, a large region marbled with dark nebulae is visible. I won’t name them all, but the largest is B174.
- Kruger 60: Listed in the astrometry as Kruger 60, this object is a double star of magnitude 9.8. It is a pair of red dwarf stars very close to each other, with an average distance of 9.5 astronomical units (AU), equivalent to the distance from the Sun to Saturn, varying from 5.5 AU to 13.5 AU.
- IC 1442, NGC 7245, NGC 7226, NGC 7175, NGC 7234, NGC 7261, NGC 7281: All these objects are open clusters.
* Equipment:

The California Nebula, NGC 1499, a cloud of gas and dust in the constellation Perseus, named for its resemblance to the shape of California. I was surprised at the amount of detail and color separation, which results from the combination of exposures in the light of hydrogen (green), sulfur (red), and oxygen (blue). This is a mosaic of three frames with a total exposure of 9 hours with the dual hydrogen+oxygen filter and 6 hours with the sulfur filter.

IC443 is a supernova remnant about 5000 light years distant. For this false colour image I captured light emitting from hydrogen, sulphur and oxygen ions and then combined in a HSO tone map i.e. hydrogen is red, sulphur is green and oxygen is blue. Throughout much of the jellyfish hydrogen and sulphur emissions are equally strong giving yellow, while oxygen is relatively weak and is only visible around the edges.
The image is an integration of 12 hours of H, 13 of O and 14 of S captured in 10 minute subframes on a QHY163M camera with Optolong filters, The telescope was a WO FLT110 with Flat4 and this was mounted on a Skywatcher AZ-EQ6. Imaging was managed by Sequence Generator Pro with PHD2 for guiding and all post-processing was carried out in PixInsight.

Another trip into space last night for the Monkey Head Nebula (NGC 2174), getting its name from its shape which, of course, resembles a monkey's head - can you see it?
It is an emission nebula located in the constellation Orion and is associated with the open star cluster NGC 2175 at its centre and is thought to be located about 6400 light-years away from Earth.

Tarantula Nebula is an impressive cosmic object, it lies in Great Magellanic Cloud, a nearby galaxy of our local group. This nebula is very rich in hydrogen, in this image we can see many complex clouds of ionized gas. NGC 2070 is a jewel for southern astrophotographers and I'm feeling so happy with this work. It's always a challenge to get this nebula because it is high on sky in rainy season here in Brazil.

The bubble and lobster claw nebula. Sh2-157, also known as the Lobster Claw Nebula, is a bright emission nebula that lies in the constellation Cassiopeia. It lies just south of the Bubble Nebula (NGC 7635).
Still seems too noisy will continue to see if i can smooth that out or perhaps just need more data.

Did you ever have a day when it felt like a dark cloud was following you around? For the open cluster of stars NGC 6520, every day is like this. On the left of the above picture are many of NGC 6520's bright blue stars. They formed only millions of years ago - much more recently than our ancient Sun which formed billions of years ago. On the right is an absorption nebula, molecular cloud Barnard 86, from which the stars of NGC 6520 surely formed. This nebula contains much opaque dust that blocks light from the many stars that would have been visible in the background. Surrounding NGC 6520 is part of the tremendously dense starscape in the bulge of our Milky Way Galaxy, the extended halo of stars that surrounds the center of our Galaxy. NGC 6520 spans about 10 light years and lies about 5500 light years away toward the direction of Sagittarius [Text adapted from APOD]

Gamma Cygni Nebula (Sadr Region)
The Gamma Cygni Nebula, also known as the Sadr Region or IC 1318, is a diffuse emission nebula that can be seen around Sadr (Gamma Cygni), the star at the center of the Northern Cross, which marks the heart of Cygnus, the Swan. Despite the name, the star and the nebula are unrelated. Even though it looks embedded in the nebulosity, Sadr is approximately 1,800 light years distant, while the nebula is much further away, at 4,900 light years.
After hearing a lot of good thing about the AZ GTI, I decided to get one and see what could happen. At first, it was really weird compared to the Star Adventurer. I took me multiple nights (almost 10) to get this picture. Flexure, Star Trails, Dithering issues and many more, but after that pain, the result was for me really nice. It allows me to make 5 min exposures, and to dither on the 2 axis (Goodbye Walking noise)
Now that everything is configure, I can setup the entire rig, in less than 20 minutes. And I'm now able to shoot mosaics, pictures coming soon :)
This picture was shoot during a waxing gibbous moon.

This intricate nebulae system is visible with binoculars with 80-90mm targetss or with a small telescope as long as you have a dark sky, even better if you use a filter (UHC, OIII): it turns out better in long-posing photos (even with a CCD camera it takes several minutes). The object will appear to consist of three very delicate nebulous filaments, arranged to form a kind of circumference. The brightest part is the eastern part, known as NGC 6992. Increasing magnifications reveal that each filament is actually made up of a network of other smaller, thinner filaments.

NGC2359 is an emission nebula located 12,000 lightyears away in Canis Major. It's also known as Thor's Helmet, given its similarity in shape to the Norse god's famous helmet. The nebula is produced by a massive, hot Wolf-Rayet star emitting a stream of charged particles known as a stellar wind that's expanding outwards to produce an interstellar bubble.
This is the second target I imaged with my new William Optics FLT 132, so second light :-). Still trying to get acquainted with this beast of a telescope, balance it properly on the AM5 mount and TC40 carbon fibre tripod. The two nights I managed to image, were partly cloudy and windy, so it was an added challenge to get good guiding. I imaged with the 1.0x FLAT68III flattener (so at the native 910mm focal length), ZWO ASI2600MC Pro and a narrowband (3nm Ha and Oiii) Optolong L-Ultimate filter.
This was a total integration time of 5h45m. Preprocessed with PixInsight and post-processed with PixInsight and Affinity Photo 2. This is the SHO palette version.

Thanks for looking and clear skies.
SH2-261 is an emission nebula in Orion. This image is an RGB integration of about 9 hours data in each of the colour channels plus 5 hours of Hα data. My kit was a WO FLT110 scope with Flat4, a QHY163M mono camera and Optolong filters. Image capture was managed by Sequence Generator Pro and PHD2. All post-processing was carried out in PixInsight.
Observed from Prachinburi, Thailand.

This represents one hour with the Optolong L-Pro filter and one hour with the Optolong L-Enhance filter.
This is three nights worth of shot and the finish of my use of the coloured camera. This is all a part of the same area in the Large Magellanic Cloud Space is black look at all the nebulosity in the area.
See if you can find the Pterodactyl head and the small man holding a spear aloft ( hint look in the white area)

The Soul Nebula, IC1848, is an emission nebula located in the constellation Cassiopeia. IC1848 is the eastern neighbour of IC1805 (the Heart Nebula: flic.kr/p/2p1mT9W), and the two are often referred to as "Heart and Soul". More information on this nebula can be found here: www.constellation-guide.com/soul-nebula/
I took this image with my William Optics FLT91 + F68III 1.0x flattener, my ZWO ASI2600MC Pro colour camera, Optolong L-Ultimate 3nm dual-band filter (Ha, Oiii), ZWO AM5 mount with ASIAir Plus for almost 6 hours (in 3, 5 and 10 minutes exposures at -10C and 100 gain). Then stacked with ASIStudio (ASIDeepStack) and processed with PixInsight and Affinity Photo 2.
This is the SHO-Hubble palette look-alike version processed in PixInsight. This is an interesting approximate process as the image taken with a colour camera and Ha, Oiii dual-band filter only has HO and not Sulfur, so it’s never going to be as good as an image taken with a monochrome camera and SHO filters.
Please see the HOO version here: flic.kr/p/2p136yR
I hope you like it.
