Welcome to the Astronomer’s area of the SAAO site, where professional astronomers can find the information they need to apply for time on SAAO telescopes and instruments, as well as explore detailed technical information about the instruments, facilities, and virtual tools.

Observing at SAAO

In keeping with its role as the National Facility for optical/infrared astronomy, SAAO makes telescope time available to qualified astronomers and post-graduate students in South Africa and at SALT partner institutes. A certain percentage of time is also granted to astronomers from around the world, to promote scientific and technological collaboration and to promote the exchange of ideas and information.
