Distributed control system for astronomical CCD-cameras

We describe the software package developed in ISTP SB RAS to control CCD cameras. The cameras are installed at astronomical telescopes and designed to record images and spectra of space objects. The system provides full-function remote control of CCD cameras through the computer network, so no operator (observer) is needed in the telescope housing. Due to the GUI application, the observer can change camera modes, make exposures, as well as download, browse, and save the images obtained to his computer. Interaction with the telescope control system allows us to correct position of the telescope when guiding an object under observation. The control system of CCD cameras has been used both at stellar and solar telescopes of the Sayan Observatory (AST33-IR, AST-14, non-eclipse coronagraph) since 2008.
