Per Aspera Ad Astra

Welcome to Per Aspera Ad Astra. We are a small company that runs a mobile observatory based on the Sardinian mountain of Montiferru not far from Oristano on the west coast (Osservatorio Astronomico di Montiferru). The observatory offers 5-day or bespoke courses in observational astronomy to teams of university students, amateur astronomers, and anyone else interested in broadening their horizons. We are planning to build permanent structures, which will allow us to invite groups of school children and university students to the observatory without cost during weekends.

Our mission is to deliver high-quality training in observational astronomy, provide access to high-end telescopes to amateurs, thrill and delight casual visitors with heavenly vistas, and perform astronomical research.

On these pages, you can find information about the observatory and book slots on astronomy courses or for observing nights at the observatory. You can also book a day visit of the observatory and its mobile planetarium. If you cannot find what you are looking for, would like to suggest a change to this website, or have a question, please contact us.

Below is a calendar showing the courses and observing nights which are open for booking. You may also be in luck and find a free event. Note that only the starting date of the 5-day courses is shown. Clicking on one of the events will take you to the booking page.
