TeleVue Focusmate™ Dual Speed Focus Mechanism

Focusing a Tele Vue telescope for visual or astrographic applications can now be smoother, more accurate and vibration free when you install the Focusmate two speed geared focus control. And you can add this fine focusing capability to any TeleVue telescope having the traditional five hole hand knob set.

The Focusmate provides:

• Attractive polished stainless steel housing and coarse focus knob with grip ring to match the size and feel of the standard knob

• Attaches easily onto either left or right side of the telescope focuser

• Smooth 6:1 ratio planetary ball system for fine focus

• Large clear-anodized fine focus knob with embedded Tele Vue logo button

• Hardware includes Delrin attachment block, spacer block, and instructions

• Accepts the optional focus position indicator kits, with choices providing either 10 Micron Resolution or 1 Micron Resolution.

• Accepts the optional Focusmate Driver motor with control software to exercise either manual or precise electronic control of focus locally or remotely.

This is an ungainly looking contraption that seems to take up way too much space hanging off the side of the telescope for our sense of aesthetics, and concerns of vulnerability. But in fact it works, it works very smoothly to provide both coarse and fine focus, and is easier to turn and smoother in its motion than some other devices we've seen and Focusmate™ is reliable.
