A design has been made for a high-end telescope system aimed at the amateur astronomer market. The design goal was to achieve high optical performance, while keeping the telescope structure light-weight and dividable so that the system is portable. Special attention was paid to the mechanical performance of the telescope structure, making the system robust and extremely reliable. Finally, the telescope was given a modular setup, making the optical characteristics adjustable for specific applications.
