Optec TCF-Leo Low-Profile Focuser

Starting Price: $1,495.00
Price as Configured: $1,495.00
Brand: Optec / SKU: OP-19740

Optec has 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 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.
