Abstract

A system for operating an astronomical observatory made up of astronomical hardware, utilizing a web browser operated by a user, and a web server connected to the observatory, wherein both the control to, and feedback from the observatory are displayed to the user in real time independent of personnel support at the observatory site. The user submits a request to the observatory via the web browser, which displays the status and results of the request. A web server, coupled to the various astronomical hardware, processes the request on behalf of the user and responds with the status and results of the request. The status and/or results ae then displayed by the web browser to the user. Requests may be made by the user interactively, or in the form of a script. The system may be used over wide area networks, like the Internet, or any other type of network.
