Design of an operational control system for a telescope system based on RACS2

A telescope has been an important way to observe the stars since it was invented. With the development of the times, people have higher and higher requirements for telescopes. In order to further improve the imaging quality and observation accuracy, the aperture of the telescope is becoming larger and larger, the associated devices are becoming more and more complex, and the working environment is becoming more and more diverse. A good telescope control system can effectively reduce labor costs and improve the utilization efficiency of observation time, so people put forward higher requirements for telescope control system. The emergence of computers has promoted the rapid development of a control system for a telescope system. Faced with the development trend of large-scale, networked and diversified observation requirements of telescopes, the control system realizes robustness and scalability on the basis of automatic observation. In this paper a control system for a telescope system based on RACS2 framework is introduced. This control system includes front-end services, back-end services, observation control components and device components. The device components are designed, which is responsible for interacting with the devices such as a telescope mount, a camera and a weather station. The remote control is realized based on Web service. The observational operation of the telescope system is tested with good results.
