We are used to seeing spectacular astronomical images in the press and on the internet. This course gives an in-depth introduction to two of the most important instruments used to create these images and explore the science behind them – telescopes and spectographs.

This course is drawn from the preparatory work for the practical residential school at the Observatori Astronomic de Mallorca. The course image shows a student at work in one of the telescope domes at the Observatori.

This course is used for training by the Faulkes Telescope Project,
