I have just returned from a trip to southern California. This area is a desert, and has so many amazing desert bird species, which I spent a lot of time photographing. Another goal I had for this trip was to visit the light-pollution free skies of Joshua Tree National Park to photograph the Milky Way. The Milky Way is tough in March as it only rises in the last few hours of the night. We had to up at 3:30 AM to photograph it! We would have about two hours to photograph it before it would begin to fade as the sun begins to rise, and those two hours were some of the most amazing of my life. Seeing so many stars and the Milky Way with the naked eye was amazing! I have never seen anything like it before. It was an incredible experience, something I will never forget!
I took tons of pictures, and this was one of my favorites. The orange light on the horizon is light pollution likely coming from a nearby city like Indio.

☄️ Comète Leonard en approche 😱.
.
J'étais obligé de la faire celle là ! J'ai tellement apprécié Neowise l'année dernière qu'il fallait que j'aille photographier la comète Leonard.
.
Elle aura attendu le dernier mois de l'année pour pointer le bout de son nez . Mais quel spectacle encore !!
.
Il est désormais possible de la voir à l'œil nu dans des bonnes conditions. Encore faut-il que la météo vous le permette. Et elle m'en a donné du fil à retordre la météo... Plus d'une semaine a check les nuages chaque nuit/aube parfois en mettant un réveil en pleine nuit (😂😭). Le ciel étant tellement couvert, il m'a fallu 2 sessions différentes pour accumuler assez de temps de pose. Un peu plus d'une heure d'expo au total pour ne garder que 35mn au final. Le pic de visibilité sera sans doute le 12 décembre mais aucune certitude si la météo me permettra de retourner shooter la comète une dernière fois.
.
Comme l'année précédente, j'ai voulu trouver un spot fort de la région pour immortaliser ce moment. En cherchant une orientation Nord-Est, j'ai alors choisi le mémorial de Vimy qui s'est proposé à moi comme une évidence. C'est un lieu que j'aime particulièrement et que je n'avais pas encore photographié 🇨🇦.

✌️ "V" zodiacal et arche hivernale ✨.
.
Au-revoir à Orion et son ciel d'hiver qui nous quittent en ce mois d'Avril. On se retrouve en Octobre pour de nouvelles astrophotos . Je n'ai malheureusement pas pu trop en profiter d'une part à cause de la météo et d'autre part à cause d'un autre projet photo qui me prend beaucoup de temps 👀.
.
🆑 Ici, c'est un peu mon Chili à moi 😂. Probablement un des meilleurs ciels de notre région (disons plutôt le moins pire). Il me faut environ 1h15 de route de la maison pour profiter de ce ciel assez correct. Situé au fin fond du Pas-de-Calais, cet endroit est classé dans une zone Bortle 4 (proche Bortle 3). La meilleure valeur de la qualité de ciel que j'ai pu mesurer ici au SQM (Sky Quality Meter) est de 21.47. Le maximum étant 22.00, il correspond aux endroits sur Terre où le ciel est le plus pur, sans aucune pollution lumineuse. Cette différence entre les 2 valeurs paraît minime mais elle est en fait énorme et la différence sur la pureté du ciel l'est tout autant.
.
🔭 Alors certes je n'ai pas la puissance des télescopes du désert chilien mais j'essaye de me débrouiller avec mon Newton 250/1000 . C'est un petit parallèle avec les moyens du bord comparé aux énormes observatoires qui sont là-bas. On voit beaucoup d'arches galactiques au-dessus des immenses coupoles, je voulais mettre à mon tour en valeur la bête . J'avais cette compo en tête du backstage : un "V" formé sous l'arche de la Voie Lactée. La cible ce soir-là était la galaxie M51, le post arrive bientôt. On peut observer de gauche à droite : le complexe d'Orion, la Voie Lactée, la lumière zodiacale, la galaxie d'Andromède et bien d'autres nébuleuses en H-alpha.

Explanation: Interstellar dust clouds and bright nebulae abound in the fertile constellation of Orion. One of the brightest, M78, on center in this colorful telescopic view, covering an area north of Orion's belt. At a distance of about 1,500 light-years, the bluish nebula itself is about 5 light-years across. Its blue tint is due to dust preferentially reflecting the blue light of hot, young stars in the region. Dark dust lanes and other nebulae can easily be traced through this gorgeous skyscape. The scene also includes the remarkable McNeil's Nebula -- a newly recognized nebula associated with the formation of a sun-like star, and the telltale reddish glow of many Herbig- Haro objects, energetic jets from stars in the process of formation.

Explanation: Follow the handle of the Big Dipper away from the dipper's bowl, until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you might find this stunning pair of interacting galaxies, the 51st entry in Charles Messier's famous catalog. Perhaps the original spiral nebula, the large galaxy with well defined spiral structure is also cataloged as NGC 5194. Its spiral arms and dust lanes clearly sweep in front of its companion galaxy (left), NGC 5195. The pair are about 31 million light-years distant and officially lie within the angular boundaries of the small constellation Canes Venatici. Though M51 looks faint and fuzzy to the human eye, the above long-exposure, deep-field image taken last month shows much of the faint complexity that actually surrounds the smaller galaxy.

Sh2-155 was first noted as a galactic emission nebula in 1959 in the extended second edition of the Sharpless catalogue.
The name "Cave Nebula" was coined for this object by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth.
Sh2-155 is a diffuse nebula in the constellation Cepheus, approximately 2,400 light-years away from Earth.

First of all, Merry Christmas to all astro folks and friends out there.
This post is about my maiden voyage with the AG14 astrograph (Recently acquired Orion Optics large Newt)
After quite some time spent on a learning to colimate the the beast using the Catseye system and other miscellaneous odds and ends required for basic setup, such as, the need for an additional counterweight. The clouds finally cleared last night and I was able to run some test shots with the new Astrograph. This image is made of a stack 30 un-calibrated 1800 sec bin x 2 subs.
Imaging telescope: AG14 astrograph 1330mm F3.8
Imaging camera: 9.2mp Sony SX814
Mount: Software Bisque Paramount MX
Focus was manually set up once with a mask and the system ran uninterrupted for the night. I am waiting for a Baader steel drive to arrive which will allow full focus automaton.
Located about 5000 light years from Earth, the center image shows the Rosette star formation region
Orion nebula, horsehead nebula, witch head nebula, and more rising over a volcanic plug in the Navajo volcanic field in northwestern New Mexico, as seen with an 85mm lens on a full frame camera.
Can you believe this image took only 1 hour of exposures to stack to this level of cleanliness? New Mexico has some of the darkest skies in the United States, and the high altitude allows for even better imaging conditions than you get in many other dark sky national parks.
And being winter with sunset so early in the day, it means you can image something like this, eat dinner, and go to sleep at a reasonable hour! This image was stacked for denoising, but the perspective is unaltered, i.e. if we had extremely sensitive eyes, this is exactly how you would see it.
La saison d'Orion est bientôt terminée, la Voie Lactée commence à se lever tôt le matin mais j'ai encore quelques clichés du ciel d'hiver à vous partager !
.
C'était surement la plus grosse sortie de cet hiver avec @remi.aug . Pas moins de 5 projets photos que j'avais en tête ont étés réalisés. Une nuit qui aura été bien prolifique avec des conditions exceptionnelles du début à la fin.
.
Un cliché pensé depuis des mois et des mois et qui m'a rendu la vie un peu difficile au traitement. Ce n'est pourtant pas le projet le plus compliqué que j'ai pu faire lors de cette soirée. La météo m'a clairement empêché de le faire plus tôt dans l'année mais une fois les tempêtes Eunice et Franklin passées, le beau temps est revenu !
.
Vous pouvez admirer les principales nébuleuses en Hydrogène (rouge) qui accompagnent notre ciel d'hiver. L'hexagone d'hiver se dessine au centre de l'image, il est formé par 6 étoiles brillantes et permet de connaître le positionnement de la Voie Lactée car elle passe en son centre.
.
La Voie Lactée est bien visible au dessus de la mer, c'est grâce à l'absence de pollution lumineuse. On peut quand même remarquer l'énorme pollution de Boulogne-sur-Mer à gauche, quelques villes très éloignées mais avec une pollution lumineuse quand même visible (Le Tréport, Dieppe, etc...), quelques bateaux et sur la droite de l'image, les premières villes des côtes anglaises.
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)

Processing Pixinsight 1.8 - I have had this data set around for a while and have never been happy with my processing results.
NGC 2359 - better known as Thor's Helmet - is an emission nebula located about 12,000 light-years away in the constellation of Canis Major. Also known as Sh2-198 and Gum 4, NGC 2359 is a “bubble” nebula measuring approximately 30 light-years across in size. It has a very complex structure and is powered by its central star, WR7, a Wolf-Rayet star, an extremely hot star that is thought to be in the pre-supernova stage.
This is my first image of 2022 and results from only 2.5 hours of Narrowband data collected on March 9 and March 29, 2022.
This image was shot with my Astro-Physics 130mm F/8.35 Telescope Platform with the IOptron CEM60 and the ASI2600MM-Pro Camera with Astronomiks 6mm narrowband fitters.
This spring's weather has been problematic, and this target is located very low in the sky between trees on my property, which gives me only about 1.5 hours of access on any given night. I only had two nights clear, allowing the capture of photons, and now it is beyond my reach, so I cannot add to it this year.
So with a paltry 2.5 hours of data - what could be done to pull an image out of the noise?
While far from a perfect image, I was a little surprised that it came out as well as it did, given the low integration time!

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).
Continuing my series of deep space objects juxtaposed with terrestrial objects, this is the Elephant Trunk Nebula setting behind a mountain here in the Smokies. The entire scene was captured at 300mm and is astronomically correct, however was obviously not captured in a single photo.
By comparison, the moon at this focal length would fit inside the dark area at the center of the nebula.
In the constellation of Ursa Major, at about 25 million light years from us lies the Pinwheel Galaxy. This beautiful galaxy has 170,000 light years across, about twice of our Milky Way.
In the photo, two types of color clusters hint on the objects present: the red-pinkish ones are the hydrogen rich nebulas where star forming is taking place and the blue ones on the spiral arms are clusters of young and hot blue stars.
This photo is a cropped reprocessing of my previously published photo.

Explanation: These two spiral galaxies make a photogenic pair, found within the boundaries of the northern constellation Draco. Contrasting in color and orientation, NGC 5965 is nearly edge-on to our line of sight and dominated by yellow hues, while bluish NGC 5963 is closer to face-on. Of course, even in this well-framed cosmic snapshot the scene is invaded by other galaxies, including small elliptical NGC 5969 at the upper left. Brighter, spiky stars in our own Milky Way are scattered through the foreground. Though they seem to be close and of similar size, galaxies NGC 5965 and NGC 5963 are far apart and unrelated, by chance appearing close on the sky. NGC 5965 is about 150 million light-years distant and over 200,000 light-years across. Much smaller, NGC 5963 is a mere 40 million light-years away and so is not associated with the edge-on spiral. Difficult to follow, NGC 5963's extraordinarily faint blue spiral arms mark it as a low surface brightness galaxy. (text: apod.nasa.gov/apod/ap120216.html)

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.

Simeis 147, also known as the Spaghetti Nebula, SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations of Auriga and Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory using a large 25" telescope. it is difficult to observe due to its extremely low brightness.
The nebulous area is fairly large with an almost spherical shell and filamentary structure The remnant has an apparent diameter of approx 3 degrees, an estimated distance of approximately 3000 (±350) light-years, and an age of approximately 40,000 years.It is about 1000 light years away and is roughly 15 light years in diameter.
Due to its size this is a 2x2 pane mosaic in order to fit the whole nebula in the frame.

The Rho Ophiuchi cloud complex is one of my favorite spring targets. Not only is the region extremely colorful, it also consists of many interesting astronomical objects:
- Rho Ophiuchi is the star within the blue reflection nebula. If you zoom into the image you can see that it is actually a 3-star system. The blue color of the nebula is produced by Rayleigh Scattering, the same process that colors our daylight sky blue.
- The Rho Ophiuchi cloud complex on the other hand is the dark nebula south of the star Rho Ophiuchi. At a distance of 427 light-years, it is one of the closest star forming regions to the solar system.
- The yellow star within the yellow nebula is Antares, the brightest star of the constellation Scorpius. It is a red supergiant, nearing the end of its live. The star has depleted the fuel supply of hydrogen within its core and is now bloated to monstrous proportions. As it goes through its death throes, the star has expelled a lot of its mass as shells of gas and dust into space. The nebulosity surrounding Antares is created by this gas and dust which is reflecting the dying star’s yellowish light.
- To the right of Antares is the globular cluster M4. Globular clusters are massive, tightly packed spheres that contain thousands, or even hundreds of thousands, of individual stars.
- Above M4 you find Sigma Scorpii. It is multiple star system of hot, young stars, emitting of UV radiation. As this high energy UV light hits the hydrogen atoms it energizes them, and the electrons separate from the atomic nucleus. When they recombine, the electrons give off a reddish-pink light which makes the gas cloud glow.
- Below Antares is Tau Scorpii, surrounded by another faint emission nebula of energized hydrogen.
- Both Sigma and Tau Scorpii share the same name: Al Niyat. They got their name from ancient Arabic astronomers and it means, "the arteries". Seeing how these stars with their red nebula flank Antares, the heart of Scorpius, it makes sense that they could be viewed as the arteries of that colossal, dying heart.
As you can see, the region around Rho Ophiuchi has it all. Its colors tell a story of darkness and light, of peaceful coexistence and violence and of birth and death.

Little Bright Blue Stars
My Interplanetary Memories
Interplanetary Travel
As the two suns illuminating the planet set behind the mountains, bright blue stars began to illuminate the sky. They looked like little blue light bulbs. They were like those little blue light bulbs that light up the scene on a wedding night. I really felt like I was at a country wedding while watching the sparkles of the stars. But I was the only guest at this wedding. There was no one around me to dance with. There was neither a groom nor a bride in this country wedding, illuminated by the stars in the sky. There was only me. Maybe this was the wedding of my eternal solitude. That night, under the stars, the whole universe witnessed this agreement that would last forever with my loneliness. It was a night when I blessed my loneliness. Thanks to this wedding, my loneliness would not bother me for many years and I would be able to continue my journey in space without any problems. It was as I thought. For many years, I never thought of my loneliness. I was very healthy mentally. Until the end of these long years. For the past year, all I've been thinking about was no longer the lost civilization of Plutonia. There was one more profound thing occupying my mind. My loneliness. I couldn't help but think about this situation. Maybe I should have made myself a new wedding of solitude. I should have remarried my loneliness. It is very difficult to make a decision in this huge vacuum of space. I want to get to the ending without hurting myself any further. I don't know yet what this ending will be. All I want is an end.
