The Efdoxos Observatory, also known as EUDOXOS, sits high on the Mount Ainos plateau on the Greek island of Kefalonia, run by the Research Foundation of Kefallinia.
About Efdoxos Observatory
Efdoxos is the first Robotic Astronomy Center in Greece, operated by the Research Foundation of Kefallinia (RFK). It is made up of two linked facilities: the EUDOXOS National Observatory of Education (NOE-E), used for teaching, and the EUDOXOS National Astronomy Centre (NAC-E), dedicated to research-grade telescopes.
History
The observatory was founded in 1993 and achieved first light in 1999. It later became one of the founding members of the Heterogeneous Telescope Network (HTN), an international collaboration of robotically operated telescopes.
Telescopes & research
Undergraduate and higher-education students can request observing time remotely, submitting schedules to the observatory's robotic telescopes rather than travelling to operate them in person — a model that reflects its role in the HTN network.
Location & getting there
Efdoxos stands at around 1,070 m on the Mount Ainos plateau, within Mount Ainos National Park — Greece's first national park to be designated a Dark Sky Park, and among the darkest, clearest skies in the country.
Visiting Efdoxos Observatory
Given its educational and research role, visiting arrangements are best confirmed directly with the Research Foundation of Kefallinia before travelling to Kefalonia.
