The Large Magellanic Cloud, a satellite galaxy of our Milky Way, is a true wonder of the cosmos. From its location in the southern sky, the Large Magellanic Cloud offers a breathtaking view of a celestial spectacle - two big, bright smudges of light hanging over the southern horizon like two stubborn clouds refusing to dissipate.
With the help of a telescope and camera, its glowing gas clouds and vibrant colours reveal a dazzling display of cosmic artistry. The colourful regions peppered across the galaxy are a massive collection of supernova remnants, stellar nurseries and star clusters. Intense radiations from those active targets energise the nearby hydrogen gases, causing them to glow like neons. Perhaps the most striking target is the Tarantula Nebula (the largest nebula seen in the pictures), a sprawling gas cloud resembling a giant spider dancing in the night sky.
(The data was acquired from Telescope Live, which I processed using Pixinsight and Photoshop).

Also known as the “Ghost of Cassiopeia”, these brightly outlined flowing shapes look ghostly on a cosmic scale. A telescopic view toward the constellation Cassiopeia, the colorful skyscape features clouds IC 59 (top border left of center) and IC 63.
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects.
The clouds of IC 63 shown in the image, about 600 light-years distant, aren't actually ghosts. They are slowly disappearing though, under the influence of energetic radiation from hot, luminous bluish star gamma Cas to the upper right.
Gamma Cas is physically located only 3 to 4 light-years from the nebulae. Slightly closer to gamma Cas, IC 63 is dominated by red H-alpha light emitted as hydrogen atoms ionized by the hot star's ultraviolet radiation recombine with electrons. Farther from the star on the top border, IC 59 shows less H-alpha emission but more of the characteristic blue tint of dust reflected star light. (courtesy APOD 10/26/2024)

The Horsehead Nebula (also known as Barnard 33 and IC434 ) is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. It is located approximately 1500 light years from earth.
This is a two pane mosaic of the Horsehead area in Orion. I originally did the lower pane (the image below) but felt that a pane above this would give a sense of completeness in the image.
This is the first image that has taken advantage of the dual rig that I have got together.

SH2-308, commonly known as the "Dolphin Head Nebula" is a HII region located in the constellation Canis Major. It is approximately 4300light years away. he massive star that created the bubble, a Wolf-Rayet star, is the bright one near the center of the nebula. Wolf-Rayet stars have over 20 times the mass of the Sun and are thought to be in a brief, pre-supernova phase of massive star evolution. Fast winds from this Wolf-Rayet star create the bubble-shaped nebula as they sweep up slower moving material from an earlier phase of evolution.
This image was captured with a ASI 2600MC Pro OSC camera and a TS-Optics 90mm CF APO f.6 Refractor (543mm focal length). I used a optolong L-eXtreme filter to capture the narrowband data.
This was my first time shooting 1000s exposures! I think it turned out pretty great, although I only have about 4.1hrs on the target.

-#85 in Explore 11/11/2016 (verificato 12/11/16 ore20:30)
Il 12/09/2015 acquisivo questo FOV con lo scopo di riuscire ad evidenziare anche le Nubi Molecolari che circondano il famosissimo ammasso aperto delle Pleiadi (M45). In questi casi occorrono cieli molto bui, una congrua integrazione e temperatura ambiente abbastanza bassa per chi utilizza le DSLR. Purtroppo velature e nubi mi avevano permesso di acquisire solo 14 frames da 300s: troppo poca l'integrazione di 1h e 10 min per pretendere qualcosa. Inoltre occorre ricordare che lo strumento fotografico era il teleobiettivo Zenit Jupiter-11A 135mm f4 (diametro obiettivo di 33,75 mm). flic.kr/p/MekcC7
Speravo in altre sessioni fotografiche per aumentare almeno l'integrazione totale, ma non sono stato fortunato.
Dopo un anno di inutile speranze ero comunque molto curioso di vedere cosa avrei potuto estrapolare da quei pochi frames. I frames combinati dal programma DeepSkyStacker (DSS) hanno creato il file.tif finale combinato, che mostrava appena un pò di nebulosità attorno a M45.
Il mio obiettivo erano le debolissime Nubi Molecolari quindi mi aspettava una elaborazione molto ardua!
E' stato necessario agire molto sulla regolazione livelli di PS e il forte "stretch" ha ovviamente evidenziato i limiti della poca integrazione. Non è stato facile controllare i diametri stellari e il rumore nei mezzitoni e nelle ombre . Questi effetti collaterali mi hanno costretto a lavorare molto con le selezioni e algoritmi riduci-rumore. Sapevo già che non potevo pretendere grande definizione dei dettagli.
Malgrado tutto l'obiettivo è stato raggiunto e mi ritengo molto soddisfatto del risultato finale, dove le debolissime Nubi Molecolari, presenti nella nostra Via Lattea, sono visibili.
Curiosità> Fa un certo effetto ripensare che fino a 15 anni fa con la fotografia analogica un risultato come questo era impensabile e irragiungibile con modesti strumenti.

On 09/12/2015 I acquired this FOV for the purpose too to be able to reveal the molecular clouds that surround the famous Pleiades open cluster (M45). In these cases it takes a long dark skies, a fair share integration and low enough ambient temperature for those who use DSLR. Unfortunately, clouds had allowed me to acquire only 14 frames of 300s: too little integration of 1h and 10 min to demand something. It is noted that the photographic instrument was the telephoto Zenit Jupiter-11A 135mm f4 (objective diameter of 33.75 mm). flic.kr/p/MekcC7
I was hoping for more photo sessions to increase at least the total integration, but I was not lucky.
After a year of futile hope I was however very curious to see what I could extrapolate from those few frames. The frames combined by DeepSkyStacker (DSS) program have created the final file.tif combined, which showed only a little nebulosity around M45.
My objective was very faint Molecular Clouds therefore waited for me a very arduous processing!
It was important to act on the adjustment levels of PS and the strong stretch has obviously revealed the limitations of little integration. It was not easy to control the stellar diameters and noise in the midtones and shadows. These adverse effects have forced me to work a lot with the selections and reduce noise algorithms. I already knew that I could not expect great detail definition.
Despite all, the purpose has been achieved and I am very pleased with the final result, where the faint Molecular Clouds, present in our Milky Way, are visible.
Curiosity> Makes a certain effect rethink that until 15 years ago with analog photography a result like this was unthinkable and unattainable with modest instruments.

An Impossible Return: A New Beginning
My Interplanetary Memories
Interplanetary Travel
I left many things behind when I left planet Earth. My friends, the streets I like to walk, the old florist uncle selling daffodils in his basket, the city where I have lived memories in every street, my favorite mountain bike, my best friend and the most beautiful girl in the world. My love. I had to leave all this behind. It was as if I had never lived. All my memories turned into dreams over time. As soon as I transitioned from the earth's atmosphere to the dark space, I began to purify myself from many of my emotions. I was turning into an emotionless person pretty quickly. That's how I was supposed to be. Otherwise, I could go back to earth to relive all the emotions I longed for. My space journey to find a planet suitable for life could have ended before it could reach its goal. So I had to get rid of all my emotions. First of all, I started to move away from my sense of longing. That way, I would be able to get away from my passion for love, albeit little by little. The thing that I had the most difficulty in leaving planet Earth was the feeling of love. I would never be able to experience true love again. When I was in the world, I had a girlfriend. She was the most beautiful being in the world. I miss her the most. Her hair, her smile, the smell of her skin. I miss her the most. I will never see her again. Every spring, there was an old uncle in the city where I live, selling daffodils in his wooden basket. Every time I left school, I would buy my girlfriend and myself a bunch of daffodils. While she was walking next to me with the most fragrant flower in the world against her nose, while I was smelling my own flower, I would watch the most beautiful girl in the world. I wouldn't turn my eyes away for once. Watching my beloved was the best moment for me. We used to do this every time after school.
I experienced the feeling of love very intensely. That's why I was sure that the first feeling I had to get rid of was love. But it was not easy for me to get rid of the feeling of love. Memories flooded my mind. In particular, during these last days of my deep space travel, memories of my life on earth had brought some feelings back to life. This was pushing me to return to planet earth. But I was so far from planet earth, my home, that it was a near impossible request for me.
I don't know if I will be able to return to planet earth, my home, from the interplanetary deep space voyage that I took off. Returning to Earth meant a new beginning for me. I would have to start everything from scratch. Maybe I was too old for that. I do not know. I've been thinking too much lately. Maybe I should stop thinking and focus on my research. I had so much time in space, but my time for planet earth was running short. This was quite the contradiction. And in the face of this situation, I was the only person who would give me the right mind.

Simeis 147, a supernova remnant also known as Sharpless 2-240, is an object typically photographed with narrowband filters, because under visible light it just appears too "poor" in comparison, mainly due to the fact that this object is extremely faint when imaged through RGB filters - and not too bright when using narrowband filters either! Narrowband data however deprives us from viewing the many other things happening around it.
Most narrowband+broadband compositions I've seen (usually H-Alpha + RGB or H-Alpha + LRGB) haven't been able to "fix" that, so I decided to give it a try, also expanding the typical already-wide FOV, to hopefully capture and visually document more of what's around.

NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called SH2-86. The whole area of nebulosity is often referred to as NGC 6820. Open star cluster NGC 6823 is about 50 light-years across and lies about 6,000 light-years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars.

🌺 Balade cosmique dans le jardin de Diane de Poitiers ✨.
.
Cet été était prévu un très court road trip de quelques jours pour visiter un maximum de châteaux de la Loire avec @amande.sen 💜. Et comme d’habitude, je ne peux pas m'empêcher de sortir faire de l’astro quand j’en ai l’occasion surtout dans ce secteur où le ciel est bien sombre. Bien-sûr j’avais des rêves d’astrophotos avec les châteaux en tête mais en sachant pertinemment que ça allait être compliqué de trouver ces lieux ouverts de nuit…
.
J’ai eu l’immense chance d’avoir accès à Chenonceau de nuit pour moi tout seul, chose qui ne se fait pratiquement jamais surtout aussi tard la nuit en été. Je suis tellement reconnaissant pour cette opportunité et je remercie infiniment la personne qui a rendu cela possible 🙏. Avancer dans l’allée centrale, voir le château au loin, se rapprocher, déambuler dans les magnifiques jardins de nuit, c’était un mélange d'émotions et un sentiment d’être tellement privilégié de me tenir ici. La magie est encore montée d’un cran quand toutes les lumières se sont éteintes…
.
🏰 Je voulais faire le maximum de projets photos que j’avais en tête pour ne rien regretter. J’en avais 2, peut-être 3 dépendant de la météo qui prévoyait des nébulosités en fin de nuit… Il y en a bien eu 3 et on commence par le dernier : un panorama ultra détaillé réalisé au 135mm avec le centre de la Voie Lactée passant juste derrière le château et la région de Rho Ophiuchi derrière la Tour des Marques, le tout s’alignant avec le superbe jardin de Diane de Poitiers. Le cadre est idyllique, on dirait que l’alignement de ces 3 éléments a été pensé tellement c’est parfait, la géométrie et les courbes menant vers le fond l’image… A ce moment, je m'imaginais les balades sous les étoiles qui pouvaient se passer ici il y a plusieurs siècles, c’est juste dingue.

This was a trial with the MeLE Nuc to see if things where right I had three nights to "play" with the whole set up. The Nuc sits under the Skywatcker ED80 so 5 long 3 m cables gone going to the laptop they all stay up on the top of the scope.
Night one did not work out at all could not get plate solve to work properly could hardly see the stars. After some two hours I gave up went to bed.
Night two I bumped plate solve exposure by more than double the time finally plate solve worked. So I thought I would try some thing to check if the system worked. On taking the very first photo it would not down load and I lost the camera. The usb cable that was supplied with the camera died. My only option was to bundle up my normal 3m cable and connect up to the camera and the Nuc and try a fix the whole lot to the scope. The whole thing looked like it was normally what I was use to seeing.
Night three I had to remove the dead cable and wrap the 3m one around the guide scope. I decided to do a real test set up the system to start on it own 6:45Pm. I sat in side the computer room and watched the sequence start flawless totally on its own. This is the result of those two nights some more 1m cables on there way to lessen the weight of cables. Plate solve has gone back to its normal 10 sec exposure time.

When Atlas was punished to bear the heavens on his shoulders, his seven daughters with Pleione - Asterope, Electra, Merope, Maia, Celaeno, Taygeta, and Alcyone – started to be pursued by the hunter Orion, who had fell in love with them and their mother. In pity of their suffering, Zeus first turned them into doves and then into stars, to protect them from the Orion’s advances who, it is said, still pursues them across the sky.
Known from, at least, the Bronze Age, the Pleiades star cluster an hallmark and leitmotiv for mythologies across several civilizations and they were/are also known as Soraya (old Persia) or Subaru (Japan).
The Pleiades is an open cluster with about 1,000 stars at about 440 light years but only the brightest are visible at naked eye, even in light polluted skies; but in a dark sky and viewed through binoculars it is a truly amazing sight. They will be gravitationally bound for another 250 million and by then it will disperse in Orion’s constellation.

The Helix Nebula is a planetary nebula formed by an intermediate to low-mass star. When a star of this size ages, it gradually sheds its outer layer, making an outward-drifting shell of gas and dust. Its core collapses to form a compact white dwarf that slowly radiates its energy away. The radiation then catches up with the gases, ionizing them and creating this astonishing scene. You can find the white dwarf star in the centre of this image; it's now about the size of the Earth.
Another interesting thing about this nebula is that the star that formed it is similar to our sun. This led to the belief that in 5 billion years, when our solar system begins to age and fade away, it might turn into a beautiful nebula just like this one.

This is a bit of an odd ball as it does not follow anthing like I have done before. I found this Dark looking structure on Stellarium but it was not named so could not select it by writing the name. I was able to use the cool feature in Nina Select it in Stellarium and it brings it into Nina as a target. The star is HIP 54413 at least I knew that part from Stellarium This is two nights worth of shots and about 6 goes at trying to edit this which is so different to how I have done all the others.
I think this is pushing the limits of the ED 80 with all this very light dusty part of the sky. The mount performed flawlessly so really happy with the two upgrades.

I captured this image in the Toggenburg Valley of eastern Switzerland from the same area as my "Rural Idyll" post. Those who have seen that image may recognize the teeth as two of the Churfirsten peaks. These rocky twins are called Schibenstoll and Zuestoll and are up to on meter of the same hight (2234 and 2235 meter).

In the constellation of Canes Venatici but quite close to Ursa Major’s star Alkaid lies the Whirlpool Galaxy, a beautiful interacting grand-design spiral galaxy. It is located at about 31 million light years from us and can be seen during Spring even with binoculars if the sky is dark enough.
Very prominently, this galaxy is interacting with a smaller one - NGC 5195 - the yellowish one on the right. As a result, large tidal tails are formed - those are the faint yellow structures around both galaxies.
Looking closer to M51, dark lanes in the spiral arms can be seen; what are these? They are compressed gas and dust clouds - the raw material for stars. And these new stars being formed are what makes the blue patches seen nearby.
One of amateurs astrophotographers preferred targets, the Whirlpool galaxy is, for sure, an amazing view. I hope you enjoy.

Many haze clouds were around.
Also the collimation of the RC-Telescope is still not very good.

IC443 (Sh2-248) a supernova remnant (SNR)is located in the constellation of Gemini. It is commonly known as the “Jellyfish Nebula”due to it's shape.
These types of objects are created by one of the most important processes in the universe - a supernova event - when a star explodes and scatters the heavier chemical elements it has made during its lifetime back into space. This material will eventually form into future stars and planetary systems.
IC443 is thought to have been formed between 30,000 and 35,000 years ago and is located about 5,000 light years away,

Second completed image of 2021 and the first complete one from my local astronomy club's dark site, an hour and a half outside of Houston. We finally had the first clear new moon weekend of the year, and myself and many others in the club decided we had to take advantage of it. It was a beautiful night with no clouds and the dew kept at bay. Had to image something unique for galaxy season and I settled on Markarian's Chain in Virgo. I framed to to get as many individual galaxies as I could in one shot.

The Veil Nebula in Cygnus, with its intricate structures, is one of my preferred nebulas in the night sky and is the result of a supernova which happened some 10,000 or 20,000 years ago.
This image is the re-processing of data taken in 2021, whose first version was published here astrob.in/93bsj3/C/ and I may say that this time I was able to achieve what I envisioned to this photo.
I hope you enjoy.

Probably the last picture with this setup, the last one with the ASI1600M / ASI183M.
I am upgrading my set up to QHY268M / QHY294M and also from the Riccardi reducer to TS-Optics RC 0.8x. (more info here)
It's a long process, to many changes.
But here is my Sunflower version.
It's an integration time of a little more than 24 hours.
From that version in 2017 astrob.in/292513/D/ to the current one, a lot of things happen.
It's a difficult object to me despite that I saw a good evolution over the years.
Always was like a defocus image, on this last picture I do all my best to correct that.
This is my last try with that focal
Now I changed my cameras but I am not sure if this change could produce better results. Maybe will check next year.
The distance to this Glaxy M63, based upon the luminosity-distance measurement is 29,300,000 light-years. Meaning that the light of the stars on this galaxy needs more than 29 million years to arrive to my camera.....
It's interesting how many other galaxies appear on the field.
Only with the PGC Catalog you could see another 7 but including the SDSS catalog up to mag. 19..... another 216 galaxies are annotated (it's full of galaxies, not stars!!)

**Prompt :**
Vaisseau spatial futuriste massif au design aérodynamique, fusion de métal poli noir et de structures luminescentes bleu électrique et orange incandescent, traversant à très haute vitesse un champ d’astéroïdes dense et chaotique dans l’espace profond. La scène capture un moment de tension extrême : plusieurs chasseurs d’escorte plus petits, aux formes anguleuses et agressives, filent autour du vaisseau principal en formation serrée, laissant derrière eux des traînées d’énergie ionisée brillantes.
L’environnement spatial est spectaculaire et riche : des centaines d’astéroïdes de tailles variées, textures rocheuses détaillées avec fissures, poussières et reflets métalliques, flottent dans toutes les directions. En arrière-plan, une nébuleuse flamboyante mélange des teintes de rouge, orange et violet, illuminant partiellement la scène avec une lumière diffuse et volumétrique. Des étoiles scintillantes et quelques planètes lointaines ajoutent de la profondeur cosmique.
Le vaisseau principal présente des détails mécaniques complexes : panneaux imbriqués, turbines lumineuses, réacteurs à fusion incandescents, lignes d’énergie pulsantes visibles sous la coque. Les moteurs projettent des jets de plasma extrêmement lumineux avec effets de distorsion thermique et particules dynamiques. L’éclairage est cinématographique avec forts contrastes, reflets réalistes sur les surfaces métalliques et effets de lens flare subtils.
Angle de caméra dynamique en contre-plongée, proche du vaisseau principal, donnant une sensation d’échelle monumentale et de vitesse fulgurante. Profondeur de champ maîtrisée, motion blur sur les chasseurs et astéroïdes proches pour accentuer la vitesse. Style hyperréaliste, rendu 8K, détails extrêmes, textures photoréalistes, illumination globale, rendu digne d’un blockbuster de science-fiction, ambiance épique, immersive et intense.

**Prompt:**
A massive futuristic spacecraft with a sleek aerodynamic design, blending polished black metal with glowing electric blue and incandescent orange energy lines, racing at extreme speed through a dense and chaotic asteroid field in deep space. The scene captures a moment of intense tension: multiple smaller escort fighters, with sharp and aggressive angular designs, dart around the main ship in tight formation, leaving behind bright ionized energy trails.
The space environment is rich and spectacular: hundreds of asteroids of varying sizes, featuring highly detailed rocky textures with cracks, dust, and subtle metallic reflections, drift in all directions. In the background, a blazing nebula swirls with vivid hues of red, orange, and violet, casting soft volumetric lighting across the scene. Countless stars shimmer in the distance, with a few distant planets adding depth and cosmic scale.
The main spacecraft showcases intricate mechanical details: interlocking panels, glowing turbines, fusion reactors burning with intense light, and visible pulsating energy conduits beneath the hull. The engines emit powerful plasma jets with thermal distortion effects and dynamic particle emissions. Lighting is cinematic, with strong contrast, realistic reflections on metallic surfaces, and subtle lens flare effects.
Dynamic low-angle camera shot, positioned close to the main ship, emphasizing monumental scale and blistering speed. Controlled depth of field, with motion blur applied to nearby fighters and asteroids to enhance the sensation of velocity. Hyperrealistic style, 8K resolution, extreme detail, photorealistic textures, global illumination, rendered like a high-budget sci-fi blockbuster, epic, immersive, and intense atmosphere.
