fumbling around in the dark for the focuser hand controller. The FCUSB also eliminates the need for a battery to run your focuser, since the motor is now powered directly from the USB port of your computer. Using the free FocusPal software, you can control the speed and direction of your motor with just mouse clicks! Third-party software that supports the ASCOM Focuser standard will also work with the FCUSB using the FCUSB ASCOM driver (may not work for all systems). Includes 8' cable.  (less)
