Observatory Controller (OCS)

The OnCue OCS (Observatory Control System) should be of help to capable DIY’ers who want to automate small observatories. It’s based on using an inexpensive and easy to work with Arduino Microcontrollers (Mega2560, Teensy, ESP32) to control some relays and sense switch closures and analog inputs and operate weather sensors which are usually on an I2C bus.

The OCS hooks up to your wired LAN (router, etc.) and provides a website which can monitor/control power, heating and cooling systems, lighting, roll-off roof, dome, and also monitor weather conditions.

There are two OCS ASCOM drivers available for a small fee.

ASCOM aware Windows software can then connect to the OCS via. the USB/Serial interface or IP interfaces.

These allow monitoring of and response to the safety status, and for operating a roof/shutter.
