Welcome to the Observatory of Épendes

Partial solar eclipse
A partial solar eclipse will take place at noon on 29 March. The Épendes Observatory will be open from 11:00 to 13:00 for those interested and offers safe observation of the sun and the eclipse under clear skies.

Messier evening
The Épendes Observatory invites you to a night of Messier objects on 29 March from 7 pm!
Our team of demonstrators will take you on a tour of the observatory and show you our instruments, the constellations of the spring sky and, depending on visibility, the planets and Messier objects.
For young and old, in a relaxed atmosphere, to discover the fascinating objects of the early sky. We also have a programme in case of bad weather.
In order to avoid waiting times and for the organisation, we are dependent on registration. Register now, places are limited!
