Crayford-Style Design: The TCF-Lynx continues the tradition of the TCF-S Temperature Compensating Focuser with a robust 2-inch Crayford-style design, providing smooth and precise focusing.
Improved Model: The updated TCF-Lynx model is not only faster but also more versatile, all within the same compact and solid focuser design.
FocusLynx Control System: Every TCF-Lynx includes the proven FocusLynx control system, which can be expanded to control a second focuser if needed. Additionally, optional accessories like 802.11 WiFi and Hand Control are available for added convenience.
2-Inch Drawtube: The TCF-Lynx features a 2-inch drawtube that accepts various 2-inch adapters designed specifically for TCF-S and TCF-Lynx focusers.
1-1/4" Centering Adapter: An optional 1-1/4" Centering Adapter is available, allowing you to add any 1-1/4-inch diagonal or eyepiece behind the focuser, enhancing versatility for visual users.
FocusLynx Hand Controller: Visual users will appreciate the FocusLynx Hand Controller, which includes a fine-focus rotary knob, enabling no-touch operation of the telescope focus for precise adjustments.
Controller Hub Requirement: It's important to note that this model requires a FocusLynx Controller Hub to function properly, ensuring seamless and precise control of the focuser.

The Optec Inc. TCF-Lynx 2” Temperature Compensating Focuser with FocusLynx Controller offers enhanced speed, versatility, and precision in a compact and reliable design, making it an excellent choice for telescope focusing needs.
