Shelyak Dome Tracker - Roll-Off Roof Kit

Shelyak Dome Tracker for Roll-Off Roofs

The Shelyak Dome Tracker was designed to allow automatic movement and closure of a roll-off roof observatory that is already outfitted with motors. The Dome Tracker is inserted between your computer, which is being used to control your telescope and other accessories, and the controller for your roll-off roof motors. Once installed, Dome Tracker can send a signal to your motor controller until the end of position switches are activated.

A Guide to the Dome Tracker Connectors

RS232 Interface: Your PC will connect to the Dome Tracker via an RS232 serial interface. Drive the Dome Tracker via an ASCOM driver or directly from a program like Prism version 6 or 7 (not included). This software will allow you to control your telescope and your dome for continuous alignment between the two during computerized object location and tracking.

Sensors: Encoders keep the Dome Tracker system appraised of your roof's location at all times.

Open: Open or close the roof with a signal from Dome Tracker.

Stop: A switch that tells the Dome Tracker to stop opening or closing the roof.

Emergency or Urgency Interface: This is a special input dedicated to a weather monitoring system or an urgent stop command that tells the Dome Tracker to close the obervatory.

The Dome Tracker requires a 12V Power Supply (user supplied). The Dome Tracker includes internal relays for electrical isolation.
