Abstract

Un Télescope Newton – Cassegrain comprend un support central (26) fixé dans un tube de télescope (20) selon l’axe optique (Z), à distance du miroir primaire (22). Un module de miroir secondaire (14, 14’) est monté amovible sur le support central, le module secondaire comprenant : une platine de collimation (32) ; un support de miroir (36) lié de manière articulée à la platine de collimation ; une pluralité de vis de collimation (60, 62) montées dans la platine de collimation et dépassant de sa face distale pour venir en appui sur une face proximale (36.1) du support de miroir ; un moyen de ressort (68) pour ramener le support de miroir en direction de la platine de collimation ; et un index (72) en saillie sur la platine de collimation. La platine de collimation est engagée dans une cavité (26.3) ménagée du support central, la cavité ayant une surface annulaire (26.4) sur laquelle vient s’appuyer une surface périphérique (32.3) de la platine de collimation, l’index coopérant avec une butée définissant la position angulaire de la platine de collimation. Le modulaire secondaire est donc interchangeable, permettant la fixation au choix d’un module secondaire Newton ou Cassegrain. (Fig. 1)
