Takahashi Temma PC Hand Controller
The Temma Hand Controller is a self-contained celestial database for the Temma-PC and Temma PC Jr. GoTo mounts. When attached to a Temma mount, you can select stars, NGC and Messier objects to view. Once an object is selected, the hand controller moves the mount to the object. It connects to the mount using an RS-232C connector. This connector is the same connector used to attach to a personal computer. When in use, a personal computer cannot be attached to the mount.
The Temma Hand Controller can also be used to manually slew the mount. Besides controlling the mount, the Temma PC controller is used to enter information about the observer’s location and time of day.
