Fields wrapped in silence #evening
#blueskyartshow
A vineyard covered in white protective sheets stretches across rolling hills under a vivid orange and blue sunset sky. In the distance, a plume of smoke rises vertically, contrasting with the peaceful landscape.

👨‍👩‍👦‍👦7 sisters family portrait
My last attempt on the Pleiades.
Easy to capture, not that easy to keep clean , in particular, collimation to get crisp star spikes.

@kat-astro-bot.bsky.social what do you see ?
Deep-sky image of the Pleiades (M45; NGC 1432/1435) in Taurus, ~440 light-years away and ~100 Myr old. The frame shows hundreds of hot B-type members, not just seven: the brightest include Alcyone, Atlas with close companion Pleione, Merope, Maia, Electra, Taygeta, Celaeno, and the Asterope pair. Wispy blue reflection nebulosity veils the cluster—strongest around Merope (NGC 1435) and Maia (NGC 1432)—with faint dusty filaments and soft halos across a wide field. Stellar cores are tight with symmetric Newtonian diffraction spikes; overall color is blue-white stars against a dense, warmer background starfield. Captured with a Newton 130/900 and Sony A7S over 6 hours of exposure.

Calm river bordered by trees in autumn shades of green and gold, with a small house partly hidden among the foliage and a misty haze above the water under a pale blue sky.

Ethereal Geometry
A close-up of a delicate dandelion seed head, its intricate filaments radiating like fine threads of light against a dark green background. The photograph captures the fragile beauty and perfect symmetry of nature’s design, each seed waiting to be carried away by the wind.

💫M33 : the Triangulum Galaxy

One of the most distant objects visible to the naked eye under very dark skies (~2.7 million ly away).

🔭Captured last summer with my 130/900 Newtonian and a Sony A7S / 24 hours total integration.

@kat-astro-bot.bsky.social what do you see ?
A detailed astrophotograph of the Triangulum Galaxy (M33), a spiral galaxy seen nearly face-on against a field of countless stars. Its bright yellow-white core fades into loosely wound spiral arms with blue star-forming regions and a distinct pink nebula, NGC 604, near the upper right of the core. The background is deep black, dotted with sharp points of starlight.

Behind the golden arches
In the shadow of global comfort, unseen hands keep the city alive.
Shanghai, 2025
Black-and-white photograph of a man pedaling a heavily loaded tricycle cart stacked with cardboard and boxes through a city intersection. Behind him, modern glass buildings and a McDonald’s sign stand in contrast, symbolizing the unseen labor supporting urban consumer life.

On the Canal du Midi, the journey isn’t about moving fast, but about learning to #relax .
#blueskyartshow
A peaceful canal scene with houseboats moored along the tree-lined waterway. The reflections of the boats and lush green trees ripple gently on the calm surface, creating a tranquil and serene atmosphere.

Walking in Shanghai streets on a Sunday afternoon, not far from Yuyuan Garden

One of my favorite views of Shanghai from the Bund. Captured just before the lights turned off.
6s exposure, trying to catch stars, but between air and light pollution, no chance.
#Shanghai #TheBund #NightPhotography #LongExposure #Cityscape
Shanghai skyline at night seen from the Bund, with bright neon lights reflecting across the river. Photo taken with a 6-second exposure just before the city lights were switched off. The photographer intended to capture stars, but the mix of light and air pollution made them invisible against the glowing skyline.

Gathering in the Park Before the Storm
#HumanOfBlueSky
Groups of people enjoy a late afternoon in the park, sitting on the grass and chatting under the tall trees. The sunlight illuminates patches of green, creating a warm contrast with the heavy dark clouds building up in the background. A scene full of calm and life, just before the weather changes.

Lines of steel, walls of stories.
#tagtuesday
A railway track runs through an urban neighborhood lined with apartment blocks. The buildings are bathed in golden sunset light, while graffiti covers a red brick wall in the background. Power lines stretch across the sky, with scattered clouds glowing in warm tones.
