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.

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.

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.

🌺 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.

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.

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.

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.

Prospetticamente attorno ad una delle più luminose stelle del cielo, la stella multipla e variabile Gamma Cassiopeiae (γ Cas), chiamata Tsih o Navi, si trova la regione di H II (idrogeno ionizzato) conosciuta con la sigla Sh2-185, e al cui interno spiccano due nebulose catalogate con le sigle IC59 e IC63.

Pensavo che riuscire a fotografare questa regione fosse una cosa più semplice invece devo ammettere che la nebulosità più debole di Sh2-185 è veramente molto evanescente e la presenza di gradienti causati da Inquinamento luminoso ha complicato le cose; quindi sono stato costretto mio malgrado ad utilizzare con decisione i tool di denoise per ridurre il rumore.

Ma ciò che ha reso più difficile elaborare questa immagine è stata la presenza della luminosa Gamma Cassiopeiae il cui riverbero abbagliava una parte dell'immagine e attorno alla quale c'era un antiestetico alone penso causato da riflessioni all'interno del riduttore 0.6X.

Ciò malgrado penso di aver raggiunto un discreto risultato.

________

Perspectively surrounding one of the brightest stars in the sky, the multiple variable star Gamma Cassiopeiae (γ Cas), called Tsih or Navi, lies the H II (ionized hydrogen) region known by the acronym Sh2-185, within which stand out two nebulae cataloged as IC59 and IC63.

I thought photographing this region would be easier, but I have to admit that the faintest nebulosity of Sh2-185 is truly very evanescent, and the presence of gradients caused by light pollution complicated matters; so, against my will, I was forced to vigorously use denoising tools to reduce the noise.

But what made processing this image more difficult was the presence of the bright Gamma Cassiopeiae, whose glare dazzled part of the image and which had an unsightly halo around it, I think caused by reflections within the 0.6X reducer.

Even so, I think I achieved a decent result.

The heart of the Heart nebula revisited using the "natural palette" with special attention to the dark nebulas there.

It a complete rework of a previous image made on SHOrgb.

A total of 57 hours of integration and a lot of intermediate version on the process.

Still I think that I could obtain more details, but this will be next year (maybe :P ).

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.

Discovered in 2011 by French astrophotographer Nicolas Outters, the Squid Nebula (Ou4) is distinguished by its elegant bipolar shape and the vivid blue glow of doubly ionized oxygen (Oiii). It is nestled entirely within the reddish hydrogen-rich emission nebula Sh2-129, also known as the Flying Bat Nebula.

Recent research indicates that Ou4 lies roughly 2,300 light-years from Earth and resides within Sh2-129. This makes Ou4 a dramatic outflow, originating from HR 8119, a triple system of hot, massive stars at the nebula’s core. With an enormous physical size of nearly 50 light-years, the Squid Nebula stands as one of the largest and most intriguing emission structures in the night sky.

Capturing the Squid Nebula is a real challenge and requires very long integration times over several nights... The perfect challenge to test my new deep space imaging rig.

Cosmic Dust Ritual

My Interplanetary Memories

Interplanetary Travel

I was watching the sunset under a red cosmic dust cloud when I took this photo. I was sitting in silence enjoying this unique view in the sky. It was a moment when I felt very, very lucky. I had not yet given a name to this nebula I had just discovered. Instead of naming this nebula, I decided to savor the moment. A nebula or nebula is a nebula structure in space made up of cosmic dust, hydrogen, helium, and other ionized gases spread over vast areas. They were the remains of a dying star. Even billions of years old stars can have an end. When I think about it, a shudder takes over my body. While the concept of the end sometimes causes peace and excitement in me, the concept of the end sometimes causes fear in me. A concept that can put you in volatile moods is the ending. Maybe I should stop thinking about the end. But I still can't stop myself from thinking about my end. There is a result that I have experienced with nebulas and which surprised me quite a bit. I always felt a tremendous sense of peace in the face of all the cosmic dust landscapes I encountered. I was able to sleep better at night. And when I woke up, I felt that my whole body was completely relaxed. The dreams I had when I slept under the cosmic dust were also different. At night, I had dreams that made me happy and did not tire my mind. I discovered that cosmic dust causes positive results in the human body and soul. However, I have never measured it scientifically. It was just an observational discovery. Even thinking about those moments gives me peace right now. Again, I can't wait to encounter a cosmic dust landscape, the nebula.

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.

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,

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.

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)

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.

Explanation: What caused the Crescent Nebula? Looking like an emerging space cocoon, the Crescent Nebula, visible in the center of the above image, was created by the brightest star in its center. A leading progenitor hypothesis has the Crescent Nebula beginning to form about 250,000 years ago. At that time, the massive central star had evolved to become a Wolf-Rayet star (WR 136), shedding its outer envelope in a strong stellar wind, ejecting the equivalent of our Sun's mass every 10,000 years. This wind impacted surrounding gas left over from a previous phase, compacting it into a series of complex shells, and lighting it up. The Crescent Nebula, also known as NGC 6888, lies about 4,700 light-years away in the constellation of Cygnus. Star WR 136 will probably undergo a supernova explosion sometime in the next million years. (text: apod.nasa.gov/apod/ap071111.html)
