TCF-Leo Low-Profile Focuser

Optec engineers have developed a new, 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 provenFocusLynx control system is included with every TCF-Leo and can be expanded to provide control for a second focuser.  The FocusLynx system includes 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 withInnovation 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. 

For owners of the EdgeHD Celestron C1400telescopes, Optec offers a set of replacement knobs for the original lock knobs which provide clearance for the TCF-Leo.  Our #19792 Sure-Lock Mirror Support Clutch upgrade includes two brass replacement lock knobs that are easily installed without tools.

With standard Optec interfaces on both telescope and camera sides, nearly any telescope imaging system can be configured.   Specify any of our OPTEC-3600telescope mounts or contactPrecise Parts for a custom adapter to fit any telescope. 

As a full 3-inch focuser, the TCF-Leo drawtube accepts any of our OPTEC-3000adapters developed for the TCF-S3 and TCF-Lynx3 heavy duty focusers.  The optional Precision Centering Adapter allows any large 2-inch diagonal or eyepiece to be added behind the focuser.  Visual users will appreciate the FocusLynx Hand Controller with fine-focus rotary knob for no-touch operation of the telescope focus.  A special discounted price for the FocusLynx Hand Controller is available at purchse.
