Optec TCF-LSI, 3" Integrated Temperature Compensating Focuser

Following the long tradition of the TCF-S Temperature Compensating Focuser, Optec's TCF-LSI features a robust 3-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 TCF-LSI has all of the control electronics integrated into the focuser body. This means that you do not need any external controller. Simply connect power and the control cable and you are ready to begin. The TCF-LSI uses the same drivers as the rest of Optec's FocusLynx family of focusers.
