An amateur astronomer for over thirty years, Sébastien Aubry captures the wonders of the universe with poetry and precision. He practices astrophotography using smart telescopes, including those from the company Vaonis, with which he collaborates, and travels the world in search of the clearest skies to reveal the fragile light of distant nebulae and galaxies. Each image is the result of a long process of signal processing, combining technical expertise, artistic creativity, and scientific rigor. He thus creates reference images that push the boundaries of our view of the cosmos.
