🔭 Dustfall of Centaurus A by
NGC 5128 (Centaurus A)The closest active galaxy to Earth (12 million light-years away), NGC 5128 is a massive elliptical galaxy colliding with a spiral galaxy. Its defining feature is a dramatic dark dust lane—a remnant of the cosmic merger—stretching across the bright stellar core. As one of the strongest radio sources in the sky, it hosts a supermassive black hole driving energetic jets visible across multiple wavelengths.Key highlights in 3 sentences:Merger Signature: The striking dust lane results from an ongoing galactic collision.Multi-wavelength Powerhouse: Emits intense radio/X-ray/gamma-ray radiation from its active core.Proximity Advantage: Its relative nearness allows detailed study of galaxy evolution and black hole dynamics.

🔭 Orion – C/2025 R3 (Pan-STARRS) Conjunction (2-panel mosaic) by
The Great Orion ConjunctionAbout a week ago, at the beginning of May, I realized that C/2025 R3 would soon be passing through conjunction with Orion.It was already frustrating enough not being able to photograph the comet anymore since it had disappeared from northern hemisphere skies, but on top of that, an exceptional celestial encounter was about to unfold without any possibility for me to capture it.That’s when I decided to contact Sascha, knowing he had access to a remote telescope in Namibia. I shared the idea with him, and he immediately agreed to join the project.Over the following days, we worked on preparing everything: determining the comet’s exact position on the day of conjunction (May 10th), finding the best possible framing, and most importantly checking whether Orion and Pan-STARRS could fit within the same field of view.This is how the project gradually took shape, eventually leading us to the final composition: a two-panel mosaic with a 90° orientation.Final framing designed and validated using Telescopius.The goal was to capture the background field and the Great Orion Nebula during the days leading up to the conjunction.Despite a very limited imaging window and a few challenges along the way (clouds, wind, and other usual obstacles), we managed to complete the mosaic over two nights with a little under one hour of integration time. All that remained was to wait for the crucial moment on May 10th to image the comet itself.The tension remained high until the very first exposure: had we anticipated the framing correctly? Thankfully, the answer was yes.So it is with great excitement and undisguised joy that Sascha and I present to you our version of the M42 – C/2025 R3 conjunction.

🔭 The Crimson Eyes of Virgo. (Markarian's Chain LRGB-Ha) by
This image of Markarian's Chain focuses on one of the most elusive structures in the central Virgo Cluster: the Hα-emitting filamentary bridge extending between the Eyes up to M86 and M84. The picture took an incredible backyard effort in collaboration with my friend Gerould Kern. We selected this target early in the winter and we knew very well the challenges ahead. Nevertheless, we were committed to get as much Ha as possible through many weeks interrupted by weather and travel. Processing this amazing view required several attempts of continuum subtraction until the pure Ha came through like a crimson river. We are very happy with the end result.

🔭 Omega Centauri: Ghost Dust and Ancient Light by
Omega Centauri is one of the most photographed objects in the southern sky, but I wanted to see what was really hiding in the background beyond the usual RGB presentation.This is a deep HaLRGB integration aimed at revealing the extremely faint Hydrogen Alpha glow and subtle traces of IFN in the field. The Ha signal here is exceptionally dim and sits right on the edge of detectability, so it took 24 hours of exposure and careful processing to bring it up without overpowering the cluster.To my knowledge, very few true deep HaLRGB images of NGC 5139 have been published, and Mauricio Christiano de Souza’s is the only other one here on Astrobin. Some noise reduction and a conservative Ha blend were essential, and I’ve tried to keep the result as faithful as possible to what the data revealed after stretching.I hope this encourages others to go deeper on objects we think we already know. Omega Centauri is not just a globular cluster; it’s sitting in a much richer and more delicate environment than most images ever show.Thanks again to my buddy Blue for assistance with data collection at our remote observatory in rural Victoria, Australia. There is also an abundance of tiny galaxies in this field, so please enjoy viewing at high resolution and playing ‘Where’s Wally’, galaxy-style, finding them all! 😀 CSAndy📷 Screenshot 2026-05-17 at 8.23.30 am.png📷 Screenshot 2026-05-17 at 8.21.33 am.png📷 Screenshot 2026-05-17 at 8.20.58 am.png 📷 Screenshot 2026-05-17 at 8.20.06 am.png

🔭 Mandel-Wilson 9: The Last Unexplored Nebula by
This molecular cloud/galactic cirrus in Apus must have one of the most romantic names in all of the sky. It has been a favourite of mine for some time, but I have only managed to image portions with my RC12. Aside from the low resolution 200mm shots the full nebula has remained elusive to me.During this current period of extended good weather, I decided to give a 3-panel mosaic with my 100mm Skywatcher Esprit a shot. In the processing I tried to bring out “wind-blown” nature of the nebula and contrast it with the wispier IFN that abounds in the direction of the SCP. The nebula has a number of further subtle reflection nebula contained therein and a lovely juxtaposition with some distant galaxies, most notably IC4633, whose spiral arms appear to form part of this wonderfully enigmatic object.

🔭 Shapley 1 / RCW 100 by
Shapley 1 (or RCW 100) is a planetary nebula in the constellation Norma. As its name suggests, this planetary nebula was discovered by Howard Shapley in 1936—making it a relatively young object. Shapley 1 forms a delicate ring, hence its nickname, the “Fine Ring Nebula.” Its average expansion velocity is approximately 25 km/s, and it is estimated to be about 7,800 years old. The description of how such a ring is formed is also fascinating.“Astronomers believe that some of these more unusually shaped planetary nebulae are formed when the progenitor star is actually a binary system. The interaction between the primary star and its orbiting companion shapes the ejected material. The stellar object at the centre of the Fine Ring Nebula is indeed thought to be a binary system, orbiting with a period of 2.9 days. Observations suggest that the binary pair is almost perfectly face-on from our vantage point, implying that the planetary nebula’s structure is aligned in the same way. We are looking down on a torus (doughnut shape) of ejected material, leading to the strikingly circular ring shape in the image. Planetary nebulae are shaped by the complex interplay of many physical processes. “The dominant color is, of course, the blue from the OIII channel, but the innermost part of the ring is also clearly interspersed with Ha.

🔭 The remarkably dynamic tail of C/2025 R3 (PanSTARRS) by
Comet C/2025 R3 (PanSTARRS) was discovered in images obtained on September 9th 2025 by the Panoramic Survey Telescope and Rapid Response System (PanSTARRS) in Hawaii. It passed perihelion on April 19th 2026 at a distance of approximately 0.5 AU from the Sun. Shortly thereafter, in early May 2026, the comet became visible to the naked eye with an apparent magnitude of about 3, primarily from the Southern Hemisphere owing to its southern declination.Prior to its passage through the inner Solar System, the comet’s orbital eccentricity was only slightly below 1, corresponding to a highly elongated periodic orbit with an estimated orbital period of roughly 170,000 years. Gravitational perturbations within the inner Solar System subsequently increased the eccentricity to greater than 1, placing the comet on a hyperbolic trajectory. Unless it experiences further perturbations, it will therefore escape the Solar System permanently.The image was acquired on May 10th 2026. From the LRGB exposures obtained over a period of approximately one hour, stacked luminance frames with individual exposure times of 240 s were generated at multiple time points. These were combined with a master RGB stack (300 s in each color channel) to produce time-resolved LRGB images separated by intervals of approximately 2.5 minutes. This processing makes it possible to study the pronounced dynamical structure within the comet’s tail. The “still image” (see revision) corresponds to the midpoint of the imaging session, at approximately 17:57 UT, with an effective temporal resolution of 13 minutes, corresponding to the interval during which sixteen 15 s luminance exposures were recorded in an L L L R G B sequence.Clear skies, the Capella Observatory team

🔭 SNR G296.5 + 10.0 RGB Ha + OIII by
G296.5+10.0, often nicknamed the “Siren Nebula”, is a large and extremely faint supernova remnant located in the southern skies. Shaped by the shockwave of a stellar explosion interacting with the surrounding interstellar medium, its delicate filaments and fragmented shell reveal the violent aftermath of a star that ended its life thousands of years ago.This image was captured remotely from Deep Sky Chile using an Askar 130SQA refractor, in collaboration with Guillaume Le Mouellic and Eric Tombarel. Beyond the intricate structures of the supernova remnant itself, the field also led to the discovery of a previously unknown planetary nebula, adding an additional layer of scientific and aesthetic interest to this deep southern sky region.The supernova remnant G296.5+10.0 — also known as PKS 1209-51/52 — most likely originated from the explosion of a massive star that underwent gravitational core collapse (“core-collapse supernova”). Current evidence suggests it came from an evolved massive star, probably a red supergiant, or possibly a star that experienced a phase of strongly magnetized stellar winds before exploding.What makes this object particularly fascinating is that:it exhibits a very pronounced bilateral structure (“double-shell” appearance),its magnetic field shows a highly unusual organization,and it contains a compact central object: 1E 1207.4−5209, a neutron star believed to be the remnant left behind by the explosion.Radio and polarization studies indicate that:the remnant is expanding into an environment already shaped by the wind of the progenitor star,this wind was likely magnetized and rotating,which could explain the remarkably symmetrical morphology of the remnant.Current estimates suggest:a distance of approximately 1.4 to 2.1 kpc (~4,500–7,000 light-years),and an age of around 14,000 years.Regarding its exact origin:it is probably not a thermonuclear Type Ia supernova,but rather the result of the core-collapse of a massive star.It is also believed that the magnetic field and stellar winds of the progenitor star prior to the explosion strongly influenced the present appearance of the remnant, making it an excellent laboratory for studying:the interaction of stellar winds,galactic magnetic fields,and the evolution of massive stars before they explode.For this image, each member of the team produced their own personal processing version, and it was Guillaume Le Mouellic who discovered, while processing his data, the presence of a previously unknown planetary nebula within the wide field of this image.His intuition led him to search for its existence across all major astronomical databases, but without success.

Numerous small collapse craters are visible along the rift, some just 2–4 km across.Particularly fascinating is the chain of aligned micro-craters that faithfully follows the main fracture. In the lower part of the image, very thin secondary fractures and delicate sinuous rifts emerge, barely perceptible against the basaltic floor.

Numerous small collapse craters are visible along the rift, some just 2–4 km across.Particularly fascinating is the chain of aligned micro-craters that faithfully follows the main fracture. In the lower part of the image, very thin secondary fractures and delicate sinuous rifts emerge, barely perceptible against the basaltic floor.
🔭 Gamma Velorum by
The bright blue star (center-left) is Gamma Velorum. This star also goes by Regor or Suhail al Muhlif, but neither are accepted as proper names by the IAU. It is a multiple star system, and one of the stars in the system is a Wolf-Rayet star, making it the brightest WR star in the sky at a magnitude of about 1.8. Just to the right of Gamma Velorum is a small part of the Vela SNR. This beautiful, twisted filament is clearly mostly OIII signal, but there is some Hα as well. There is much more diffuse Hα throughout the background. This is all part of the larger Gum Nebula, the largest emission nebula visible in our night sky.In the upper-left of the image is a young open cluster with the designation NGC 2547.In the lower-left corner of the image is a small reflection nebula that caught my eye. I was delighted to find this is the very first entry (vdbH 1) in the Southern Hemisphere extension of the Van den Bergh catalog of reflection nebulae created in 1975 with William Herbst from Cerro Tololo, Chile. In the upper-right corner of the image is an ovular object that looks like it could be a planetary nebula, but I find no mention of it in HASH, CDS, or planetarynebulae.net. The center coordinates for this mystery object are: 08 27 43 -49 00 07. I tried to find a central white dwarf and failed. It’s in several other people’s image, so I would be surprised if no one has researched it before. If anyone has any information on it, let me know. I suppose it’s also possible it’s just a weird part of the Vela SNR, but it has a strikingly different appearance to my eye (less sharp).In processing, I tried to bring out the beautiful star field, and some of the dust while still making the Vela SNR the central feature. This is cropped from a larger field to create a stronger composition. Definitely one of the nice things about the IMX455 sensor is the ability to crop aggressively and still have plenty of resolution to play with.This was captured from San Pedro de Atacama, Chile during a deep sky astrophotography workshop I was leading. My first time capturing Southern Hemisphere skies in person. I had a great time, and can’t wait to return!~Nico

🔭 The cataract plummets down three thousand feet by
The Deer Lick Galaxy is NGC 7331, a bright spiral galaxy located in the northern Pegasus constellation, about 45 million light-years from Earth, often regarded as the 'twin brother' of the Milky Way. It is very close to the Stephan's Quintet galaxies and is often photographed together with them. Last July, the Deer Lick Galaxy experienced the supernova SN2025rbs, which can be clearly seen at the core of this image, its brightness already surpassing that of the galaxy's core. With long exposure, one can also see obvious IFN (interstellar illuminated dust) and Hα emission nebulae in the surrounding sky area, especially the Hα nebulae, which flow down like waterfalls. This sky region also contains a large number of small galaxies of various shapes and colors, which is quite interesting.

🔭 Tidal Swirls of Fornax: (Fornax A and B) / NGC 1316 & NGC 1317 by
Fornax A (NGC 1316) and Fornax B (NGC 1317) are amazing galaxies in Fornax located apprx. 60 MLY. Fornax A is a giant lenticular radio galaxy scarred by past galactic mergers, it glows with dark dust lanes and sprawling stellar halos, while nearby Fornax B shines more softly amid the rich backdrop of distant galaxies. Fornax A displays multiple looping swirls and lanes of interstellar dust embedded within its diffuse stellar halo. These complex structures are believed to be remnants of the past galactic mergers and tidal interactions, where absorbed spiral galaxies left behind warped dust features and disrupted stellar streams. Another great data acquisition by Dark Matters astrophotography in the dark skies of Chile.

🔭 The Trilobite Nebula SNR G206.9+02.3 by
A special dedication to my mother, who passed away yesterday.Sara Mendez01-05-1955 - 05-31-2026The Trilobite Nebula: Captures its unique fossil-like, segmented shell shape.SNR G206.9+02.3 (also known as PKS 0646+06) is a faint, rarely photographed galactic supernova remnant located in the constellation Monoceros. It represents the expanding filamentary debris shell of a massive star that ended its life in a cataclysmic supernova explosion.Distance: Estimated to be between 7,000 and 7,200 light-years (approx. 2.2 kiloparsecs) from Earth. Age: Approximately 64,000 years old, placing it in the older, radiative phase of its cosmic evolution. Size & Scale: Spans an angular diameter of roughly 50 arcminutes—making it larger than the full Moon in the night sky. Its current linear diameter is about 18 parsecs (approx. 58 light-years). Expansion Velocity: The blast shockwave is plowing through the interstellar medium at a speed of 86 kilometers per second.Astronomers and astrophotographers catalog this target as highly elusive because it is overshadowed by prominent celestial neighbors like the nearby Rosette Nebula. It sits immediately to the west of the massive Monoceros Loop (SNR G205.5+00.5).Though faint, deep narrowband astrophotography reveals a distinct double-shell filamentary structure. The remnant glows primarily due to ionized gases, exhibiting strong emission lines from Oxygen (O[III]) which provides delicate blue/green highlights, mixed with Hydrogen-alpha (H\(\alpha \)) red filaments. Because its unique outer shape resembles a fossilized prehistoric trilobite, some amateur astronomers informally refer to it as the "Trilobite Nebula."
