-
Lightweight and strong structure
-
Rapid thermal adaptation with the open structure
-
Primary and secondary cellular mirror, reducing the weight and faster thermal adaptation
-
4 positions secondary mirror, manual or motorised rotation. Is it now possible to have 4 telescopes in one : add a Barlow and a reducer corrector with their own camera system, and a visual lens
