TI Series
Wynne Prime Focus Astrograph
Main Technical features
The TI WPF Series Astrographs is a super‑fast, large‑aperture imaging systems. Thanks to a specially designed large Wynne corrector (164 mm diameter), it achieves an impressive f/2.6 focal ratio with excellent field correction and coverage. The optical design ensures very low obstruction and easy collimation thanks to the limited number of optical elements.
It comes with full carbon/aluminium sandwitch structure, Lightweight Quartz primary mirror (as Option for the TI WPF 45) and integrated electronic system for a full telescope control via WiFi and Ethernet connection for remote observatory.
The WPF Astrograph delivers a very high hourly imaging throughput, making it particularly well‑suited for covering the largest possible sky area in the shortest time — ideal for all SSA operations
