Shoestring Astronomy FCUSB
Features
The FCUSB is a product that allows you to control a DC focus motor (or any DC motor for that matter) by way of a USB port and software on your computer. If you are already using a computer in your observatory for other reasons, this provides a way for you to focus your telescope without fumbling around in the dark for the focuser handcontroller. It works best with 5V focus motors such as the newer style JMI Motofocus, but can also work with 9V or 12V motors. Motors requiring up to 100mA of current will work with the FCUSB. To date, the FCUSB has been tested with the JMI Motofocus, Moonlite DC motorized focusers, Orion AccuFocus, Meade 1209, Televue Focusmate Driver.
