The TCF-Leo is the newest in their line of temperature compensating focusers. This thin low-profile focuser has a minimum thickness of only 1.25-inches and 0.35-inches of travel or about 9 mm.
This TCF-Leo will help many imagers struggling with minimal back-focus on scopes such as the Celestron EdgeHD C1100. It is designed to fit between the mirror lock-knobs on the C-11HD and will work well with the Innovation Foresight On-Axis Guider as well as the large Perseus 3-inch port.
This 3-inch focuser is for telescope installations where back-focus is at a premium. With the width of a typical 1.25-inch 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 is included with every TCF-Leo and can be expanded to provide control for a second focuser. The Optional Gemini Hand Controller can be included with an additional charge (#OP-19752).
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 (55 mm), 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 it'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 an EdgeHD C1400 telescope, we offer a set of replacement knobs for the original lock knobs which provide clearance for the TCF-Leo. Item #OP-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 the Optec-3600 telescope mounts or contact OPT to get a custom adapter to fit any telescope.
As a full 3-inch focuser, the TCF-Leo drawtube accepts any of the Optec-3000 adapters developed for the TCF-S3 and TCF-Lynx3 heavy duty focusers. With the optional custom Precision Centering Adapter any large 2-inch diagonal or eyepiece may 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.
