Used Optec TCF-Si Focuser - SOLDMechanically, 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 now accomplished via direct serial connection between the focuser and computer.
The unit adds 3.5 inches to the telescope's back focus as measured from the front to the end of the drawtube when at the mid-focus position. The total travel of the drawtube is 0.6 inches or 7000 steps. 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.
