Optec TCF-Si Focuser

This TPO focuser package was developed by Optec and includes an adapter to fit to your TPO 10 to 24" RC Telescope and a 12 foot long USB to RJ12 cable for computer control. 

Mechanically, the Optec TCF-Si is a robust Crayford style motorized focuser with high repeatability, no play and nearly zero backlash of only 0.0013 inch. Optecs implementation is ideal for applications which require exact focus such as CCD imaging or film astrophotography. A geared stepper motor rotates the drive shaft with one step rotation of the motor equal to a 0.000086 inch movement of the drawtube. Focuser control is accomplished via direct serial connection between the focuser and computer.  The TCF-S focuser can easily handle cameras and instrument packages weighing up to 10 pounds. The TCF-S can be used with a PC for automatic focus with some of the popular camera control software.
