Telescope Autoguider

This project uses the Raspberry Pi camera module as a star-tracker while using the PiXi to provide time-critical control of a computer-controlled telescope.

The RS232 ports on the PiXi together with the open-collector provide interfaces to the telescopes auto-guider port, RS232 communications port and even the handset port.

With the Meade LX200 series of scope in mind here, the combination of the Raspberry Pi and PiXi, with the addition of a small back-lit LCD display and custom keypad, the PiXi & Raspberry Pi could also provide a convenient replacement to the original telescope hand controller.
