The clearest sky in eastern Sardinia
The Lanusei Astronomical Observatory, a branch of the Cagliari Astronomical Observatory (INAF), was chosen precisely for the exceptional quality of its night sky. Far from the light pollution of the coasts, at nearly 600 metres altitude, the starry horizon of Lanusei is among the clearest in all of eastern Sardinia. On some summer nights it is possible to see the Milky Way with the naked eye.
