À travers l'objectif d'un télescope Schmidt-Cassegrain Celestron de 14 pouces, associé à une caméra astronomique refroidie par effet Peltier, la surface de la Lune révèle ses détails complexes avec une clarté remarquable. Ce dispositif avancé capte les textures subtiles et les ombres des paysages lunaires, offrant un aperçu vivant de la beauté persistante de notre voisin céleste.

    1. To achieve this level of sharpness, the C14 telescope requires regular collimation checks. The atmospheric conditions were also very stable, and stacking several thousand frames allowed for a final, wavelet-sharpened image of the moon.

        1. AutoStakkert is a good option for this, though alternatives like AstroSurface also exist. It analyzes each frame to identify a reference frame, then uses that to set alignment points and stack a percentage of the sharpest frames into a single image based on the best reference frame it finds.

          1. For high-speed video data, such as lunar and planetary work, we record directly to a laptop. For long-exposure deep space imaging, each subframe, typically 3–5 minutes, is saved to a Raspberry Pi before transferring to a computer for processing.
