Description

Details

Optec 3” TCF-S3 Focuser

The TCF-S has a new big brother - the TCF-S3. This 5 pound focuser has all the same features of the TCF-S but is just bigger and stronger. With the every increasing size of CCD cameras and associated instruments, the need for a precision digital focuser that can take the weight and is compatible with most of the camera control software available is now met.

No corners were cut with this model. The massive drawtube has a 3.00-inch I.D. and is made from 7075, the strongest of the commercial aluminum alloys. To prevent any slippage common to Crayford style focusers, the drive rod is pressed onto the drawtube with a force of about 500 pounds. The TCF-S3 can take this extreme pressure because the drive rod is made from a ground bar of high speed steel with a diameter of 0.375 inch. Hardened rails of stainless steel are embeded in the drawtube to engage the drive rod and take the strain.  

The total linear travel of the drawtube is 1.00-inch with a resolution of 0.0001-inch. Like the TCF-S, a control box with IN and OUT pushbuttons, serial computer interface and digital display control all functions of the TCF-S3. All other features of the TCF-S3 are similar to the TCF-S. It uses the same cables, temperature probe and the new remote keypad.

You can read more about the TCF-S by following the link in the "Images/Articles" tab. Please remember that you will need to choose your telescope mount & control cable from the "Accessories" tab, and, depending on your set-up, you may need other items.
