Since I have insane comet envy, here's reposting of my shot of C/2023 A3 (Tsuchinshan–ATLAS) from last year. Hopefully I will get to image one of these current comets at the EOM. #comet #astrophotography #astronomy #spacethings #fyp
This striking astrophotograph captures Comet C/2023 A3 (Tsuchinshan–ATLAS) in exquisite detail as it sweeps through a star-filled sky. The comet’s brilliant nucleus glows an icy blue-white, surrounded by a faint greenish coma produced by sublimating gases like cyanogen and diatomic carbon. Its dust tail stretches diagonally across the frame, a luminous gray plume that gradually fades into the darkness. Subtle striations reveal the intricate flow of dust and gas sculpted by solar radiation and the solar wind, while variations in brightness hint at the comet’s rotation and outgassing jets. Behind it, a dense field of stars — from warm orange giants to cool blue dwarfs — forms a glittering backdrop that emphasizes the comet’s sheer scale and motion. The image likely captures C/2023 A3 near its brightest phase, when it developed its long, fan-shaped tail and became one of the most anticipated comets of its generation. It’s a portrait of motion, impermanence, and cosmic grace — an icy traveler from the outer solar system burning brilliantly for a fleeting moment before continuing its journey into the void.

New image! Desperately tried to get to 100 hours broadband but I'm quickly running out of actual night skies here in the UK and the moon isn't helping. Think this is finished for this year! 85 hours BB and 45 hours NB. Description in the alt text. #astronomy #astrophotography #space #fyp #askar #zwo
Highly detailed astrophotograph of the M81 Group captured in RGB and H-alpha (RGBHA), showcasing over 130 hours of total exposure time — 85 hours in broadband and 45 hours using a duo narrowband filter. At the center is the majestic spiral galaxy Messier 81 (Bode’s Galaxy), glowing with a bright yellowish core and sharply defined, bluish spiral arms. The dust lanes are speckled with magenta regions (HA) indicating star formation. To the lower left lies Messier 82 (the Cigar Galaxy), appearing elongated with a vibrant magenta-red core due to intense hydrogen-alpha emission. Below and to the right of M81 is NGC 3077, a distorted dwarf galaxy with a pinkish hue. The entire field is richly filled with faint galactic cirrus — wispy, smoke-like structures of dust and gas known as Integrated Flux Nebula (IFN), subtly illuminated by the collective light of the Milky Way. These ghostly veils drift across the frame, enhanced by the long integration time and narrowband sensitivity, giving the image a sense of depth and ethereal motion. Background stars vary in size and color, scattered across a black canvas peppered with additional distant galaxies and soft glow from hydrogen emission regions, all captured in extraordinary clarity.

Here's 124 hours on the Dark Shark Nebula. 3 panel mosaic with 40 hours of duo NB data included for some HA in the Wolf's Cave. Finally done for now. This one took over a year. 😅 #astronomy #astrophotography #dso #space #spacethings #fyp #askar #zwo
Drifting through the vastness of interstellar space, a trio of enigmatic nebulae emerges from the darkness, sculpted by cosmic winds and the faint glow of distant stars. This deep-space image, captured over 100+ hours of broadband and narrowband exposure, unveils the haunting beauty of LDN 1235 (The Dark Shark Nebula), the Angler Fish Nebula, and the Wolf’s Cave Nebula—each a unique sentinel of the galactic sea. At the heart of the composition, LDN 1235, the Dark Shark Nebula, stretches its dusty tendrils across the void, its shadowy form eerily resembling a deep-sea predator lurking in the cosmic abyss. This vast molecular cloud, a delicate interplay of starlight and dust, remains a silent witness to the slow dance of stellar evolution. Nearby, the Angler Fish Nebula glows faintly, its subtle ionized gases hinting at the hidden forces sculpting its ethereal shape. Like its namesake from Earth’s deepest oceans, this nebula appears as a predator of the dark, its gaseous filaments illuminated by the faint glow of embedded stars. Completing the celestial trio, the Wolf’s Cave Nebula resides in a hushed corner of the universe, its soft reflection and emission layers whispering of hidden stellar nurseries. Its delicate glow emerges through veils of interstellar dust, a reminder of the quiet but relentless forces that shape the cosmos. This image is a testament to the perseverance of both the universe and the observer—over 100 hours of captured light reveal a rarely seen world, where cosmic creatures drift between shadow and starlight, forever suspended in the silent ocean of the Milky Way.

What feels like relentless weeks of cloudy skies have finally opened up enough to collect some light on an ongoing project (my white whale). Here's the Wolf's Cave nebula. Still alot more NB data needed but its coming along nicely. Details in the alt text. #astronomy #astrophotography #space
This astrophotograph captures the Wolf's Cave Nebula (van den Bergh 152, VdB 152) in a combination of broadband and hydrogen-alpha (Ha) data. The nebula appears as a faint, dusty region set against a rich backdrop of stars, with dark brown and gray interstellar dust clouds weaving through the frame. The most striking feature is the elongated, ghostly shape of the Wolf's Cave Nebula itself, located on the right side of the image. This reflection nebula is partially illuminated by an embedded star, creating a faint glow against the dark molecular clouds. Wisps of interstellar dust extend outward, partially obscuring the star field behind it. Incorporated hydrogen-alpha data reveals faint red emissions, particularly along the right edge of the image. This suggests the presence of ionized hydrogen gas, contrasting with the cool, dusty structures dominating the scene. Scattered throughout the image, countless stars of varying colors—blue, yellow, and white—dot the field, emphasizing the vastness of space. The overall composition showcases the intricate interplay between dark nebulae, reflection nebulae, and faint ionized gas, making this a complex and dynamic deep-sky scene.

A moody, dramatic view of Brighton's West Pier ruins, framed by rusted metal pillars on the pebbled beach. The skeletal remains of the once-iconic pier stand against the turbulent sea, with dark storm clouds looming overhead. Signs on the pillars warn against trespassing, emphasizing the structure’s fragile and abandoned state. The scene exudes a sense of eerie beauty and nostalgia, reflecting the pier’s storied past. Brighton’s West Pier, designed by Eugenius Birch, opened in 1866 as a grand pleasure pier, attracting Victorian-era tourists with its elegant design and entertainment spaces. In its heyday, it was a hub for concerts, theaters, and seaside leisure. However, after its closure in 1975, the pier fell into disrepair. Storm damage and fires in the early 2000s left only the skeletal remains standing in the sea, making it one of Brighton’s most hauntingly beautiful landmarks. Today, it serves as a poignant reminder of the city’s rich seaside history.
