Les tubes sont disponibles en trois longueurs, 7,5 mm, 15 mm et 40 mm, et sont équipés d'un filetage interne T-2 à une extrémité et d'un filetage externe T-2 à l'extrémité opposée. Le filetage interne complet et le noircissement tuent toutes les réflexions de lumière parasite.\u003c\/p\u003e\n\u003cp\u003e Les tubes d'extension T-2 sont utilisés dans tout le système ASTRO T-2 System™ pour fournir un espacement approprié des composants du système. Le télépresseur Alan Gee Mark II peut être configuré de différentes manières qui bénéficient de la possibilité de faire varier l'espacement de l'objectif par rapport à la caméra ou à l'oculaire. Les tubes d'extension offrent un moyen sûr de faire varier les rapports de projection (séparation oculaire à caméra), pour le système OPFA (projection afocale et oculaire), et le MPCC utilise les tubes d'extension T-2 pour localiser et coupler avec précision le correcteur de coma à oculaires. Vous pouvez utiliser les tubes d'extension partout où vous avez besoin d'espacer et de coupler avec précision l'un des composants T-2, dans des configurations de votre propre conception. \u003c\/p\u003e\n\u003ch3\u003eSpécifications techniques \u003c\/h3\u003e\n\u003ctable style=\"box-sizing: inherit;
