The University Observatory hosts a range of astronomical telescopes for research, teaching and outreach. It is an outpost of the astronomy group at the School of Physics & Astronomy in St Andrews.

The first dome visible from the street is on top of the Scott-Lang building, left in the image. The building is today occupied by the Centre for Research into Ecological and Environmental Modelling (CREEM). The dome contains a 50-cm reflecting telescope with a spectrograph (currently not in use).

Further down the path towards the sports grounds is the Gregory building with the large dome of the James Gregory Telescope.

The 54 year old 37″ James Gregory Telescope, the largest operational telescope in Scotland, is the undisputed highlight of the observatory. It is mostly run by postgraduate students and postdocs and is almost exclusively used for research projects. The JGT participates for example in the hunt for extrasolar planets as part of the Super-WASP collaboration and in the program TOYS, short for “Time-domain Observations of Young Stars”. It is also used for teaching on undergraduate and graduate level, for example, as part of the Observing School of the Scottish Universities Physics Alliance.

The Napier building with its two small domes is towards the north of the Gregory. This building is in essence a student observatory. The domes of the Napier house two Schmidt-Cassegrain telescopes with 25 (10″) and 40 cm (16″) aperture. Students can receive training on these telescopes and use them on their own for visual observations, astrophotography, and research. A number of smaller mobile telescopes are available. A class room is available for talks and project work. The student’s astronomical society Astro-Soc has an observing room and organises stargazing nights.
