More information

Optec engineers have developed a low profile, yet extremely robust 3-inch focuser for telescope installations where back-focus is at a premium. With the width of a typical 1-1/4" eyepiece, the TCF-Leo provides a unique focusing solution for the Celestron EdgeHD and other telescopes with limited flange-to-focus distances. The proven FocusLynx control system operates the TCF-Leo and can be extended to provide control for a second focuser and supports the optional 802.11 WiFi and Hand Control accessories.

The unique shape of the TCF-Leo is designed to fit neatly between the lock and focus knobs of the Celestron EdgeHD C-11 telescope OTA. With a center-to-edge distance of about 2.2-inches (55mm), the TCF-Leo works exceptionally well with Innovation Foresight's On-Axis Guider, providing clearance for large cameras and filter wheels above either of the flat edges of the TCF-Leo. Additionally, the TCF-Leo's 3600 receiver fits directly on to the large 3-inch port of the Perseus Instrument Selector for ultra-fine focus of a large format camera.

The TCF-Leo supports several draw tube options including the Optec 3000 dovetail, a DSI 3.5" receiver, and a 3-inch split clamp for Wynne Correctors. You can select the option that works best for your system.
