Technical Innovations Innovations Robofocus RF-3 International (No AC Adapter)

The Robofocus RF-3 International (No AC Adapter) by Technical Innovations:

Technical Innovations' RoboFocus is a remote focus driver to be installed on your existing telescope focus mechanism. RoboFocus provides digital control and feedback of the focus position using a specialized stepping motor controlled by a microprocessor. To use the RoboFocus from a remote location, you send the commands from your computer to change the focus position and receive back digital position information. You will check the results by taking a CCD image to judge if the focus is where you want it. Many users find that they can focus perfectly in only 3-5 minutes after taking only a half dozen fast star images.


With RoboFocus, you can make tiny changes to the focus setting so that you can finally take full advantage of the resolution of your optical system for either visual or imaging applications. You can repeat a focus setting at will, and you can always get back to a setting that you found to be optimal. And, you can make these focus changes from your control room or observatory.
