Absent du forum depuis quasi deux ans, j’avais en t\u00eate l’id\u00e9e de r\u00e9aliser un astrographe.
\n C’est chose faite. Dur\u00e9e du projet 1 an et demi, c’est tr\u00e8s tr\u00e8s long.
\n C’est un Newton de 300 FD 3,6
\n L’optique est en quartz et r\u00e9alis\u00e9e par Mr Gri\u00e8re (Mirro-sh\u00e8re).
\n L’usinage des pi\u00e8ces (alu a\u00e9ronautique 7075) a pris pas mal de temps. Le plus long a \u00e9t\u00e9 de trouver un tourneur fraiseur qui accepte le travail.
\n Le tube est en carbone 5mm \u00e9paisseur plein.
\n Le po est en 3′, le correcteur est un Wynne de 3′
\n Le primaire 305mm, le secondaire 120mm.<\/p>\n

Bonne soir\u00e9e.<\/p>\n
