ShoeString Astronomy sells a nice adapter to let you control motorized focusers via your PC. This adapter, the FCUSB (and it's cousins, the FCUSB2, JMI PC Focus Control, and TeleVue FocusMaster) control a wide range of motorized focusers that use simple DC motors and give you fine control over your motorized focuser. Or at least they do if you have a PC. If you have a Mac, you're out of luck.

ShoeString Focus fills this void by giving you the same functionality as ShoeString's included FocusPal software. It will control the FCUSB, FCUSB2, JMI, and Televue adapters on any Mac running OSX 10.4 (Tiger) or 10.5 (Leopard). (Some 10.3.9 systems may work as well). For the Televue FocusMaster, the position indicated by the digital caliper is shown as well.
