ASA H400 F2.4 Telescope System


Ideal for astronomical widefield imaging, offering fast, high resolution wide field pictures of the night sky. This fact made the hyperbolic ASA telescope of choice for the professional project Super Wasp II, a program searching for EXO-planets, which is supported by eight universities, including the Universities of Geneva, Leicester, Queens Belfast, Warwick and the German Space Agency DLR at Berlin. The H400 has also been chosen for satellite tracking given its wide field and extremely high resolution.
