Ce t\u00e9lescope de type Newton de 203 mm, ouvert \u00e0 F\/D 6, est un instrument r\u00e9alis\u00e9 par Gilbert Da Costa et Pierre Mourg\u00e8s.

L\u2019optique (le miroir) a \u00e9t\u00e9 r\u00e9alis\u00e9e au sein du groupe en suivant les conseils \u00e9clair\u00e9s de l\u2019ouvrage de Jean Texereau (http:\/\/www.astrosurf.com\/texereau\/<\/a>)<\/em>.<\/span><\/p>\n

Il a \u00e9t\u00e9 r\u00e9alis\u00e9 en deux \u00e9tapes. La premi\u00e8re en 1986, avec un tube de section carr\u00e9e, sans motorisation : ci-dessous pr\u00e9sent\u00e9 par Gilbert Da Costa.<\/span>\"\"<\/a><\/p>\n

La seconde \u00e9tape a consist\u00e9 \u00e0 le mettre dans un tuyau plastique de 200 mm de diam\u00e8tre (qui sert g\u00e9n\u00e9ralement \u00e0 des canalisations), \u00e0 changer sa monture en utilisant des pi\u00e8ces m\u00e9caniques de 2 CV, et enfin, par l’adjonction d’une motorisation sur un axe, qui a \u00e9t\u00e9 r\u00e9alis\u00e9e gr\u00e2ce \u00e0 un moteur qui \u00e9tait initialement un programmateur de machine \u00e0 laver.<\/span><\/p>\n

Il peut \u00eatre \u00e9quip\u00e9 d’un filtre solaire pleine ouverture (comme ici). C’est un peu le \u00ab tout-terrain \u00bb du club.<\/span><\/p>\n
