High-zoom-capable tracking telescope
A high-zoom-capable tracking telescope is used for initial target acquisition and tracking. This telescope is a version of the PVP Advanced EO Systems (PVPAEO) (Orange, California) TH-2 system and is shown in figure 9. The tracking scope uses a Cosmicar Pentax (Pentax CCTV Lens Division, Golden, Colorado) 55x zoom with 2x extender with a PULNiX TMC-745i high-contrast black and white camera. The TMC-745i has sensitivity in the near IR also (to ~1µ ). The TH-2 is mounted in a sealed enclosure for protection against the elements.
