Following the long tradition of the TCF-S Temperature Compensating Focuser, Optec’s TCF-Lynx features a robust 2-inch Crayford-style design for smooth focus.  The updated model is faster and offers greater versatility in the same compact, yet solid, focuser design.
The proven FocusLynx control system is included with every TCF-Lynx and can be expanded to provide control for a second focuser.  The FocusLynx system includes optional 802.11 WiFi and Hand Control accessories.
As a robust Crayford style 2-inch focuser, the TCF-Lynx drawtube accepts any of our 2-inch adapters developed especially for the TCF-S and TCF-Lynx focusers.  The optional 1-1/4″ Centering Adapter allows any 1-1/4-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.
Note that this model requires a FocusLynx Controller Hub to function.
