The quality of the final image depends on many factors including the level of acc… That is called prime focus but I won’t be covering that here. In astrophotography, we use the "500 Rule" it allows to take pictures of the night sky without noticeable star trails: divide 500 by the focal length of your lens and you will obtain the maximum exposure time. Answer One great alternative option, for a set up that is relatively lightweight, portable and affordable is to use a star tracker for the mount. salut normalemenr le code devrait fonctionner ainsi que le cablage (auquel tu peux meme enlever les led du coup) quand tu achetes l'arduino tu vois sur la photo si la carte a des pates de soudées, mais dans le pire des cas, meme si tu en recois un avec des pates, tu peux les couper avec une pince :). 2 days ago 11 Celestron CGX Equatorial Mount (Premium Option) 12 Final Words.
