ABOUT US

Former CNRS observatory

The atmosphere of Mount Chiran is of an increasingly rare quality,
it is now open to anyone curious about celestial objects.
The refuge also allows hikers to enjoy a stopover on a mountain route.

With the help of an astronomer, you can take the time to stay a full night to observe the Moon, planets, stars, galaxies and many other remarkable astronomical objects.

For astronomy clubs or amateur astronomers: weeks of missions are possible and welcome! Information on request.

The astronomical observatory whose management had been entrusted to the association ABCDE today operates independently of the association, while remaining linked to it. The Chiran receives curious from the sky as amateur astronomers, either in groups or isolated. Accommodation is provided at the refuge which has 16 beds (4 bedrooms with 4 bunk beds), as well as a large common room and kitchen.

The site also provides meals, prepared by our chef. Please note, meals prepared on site are only offered in the evening. However, if you are roaming, you can order picnics for lunch in advance.

An experienced astronomer hosts astronomy evenings in the dome, which is equipped with a 406 mm telescope, built by members of the association and the observatory's managers.

The refuge took place in the premises that once housed scientists ...

You will also find there numerous documents on astronomy, flora and fauna, the discovery of the Chiran massif and the Verdon Regional Natural Park.
You can stop there for a day hike, or for the night only if you take part in an astronomy evening.

Characteristics of the telescope and instrumentation

In the cupola :

Newton Serrurier telescope on fork mount

  • Diametre = 406 mm

  • Focal length = about 1.8 m

  • Aperture (ratio F/d) = about equal to 4.5

  • Automated and self-guided telescope for astrophotography

This makes it a rather "open" telescope, and therefore more specialized for deep sky objects (nebulae, galaxies...).

In parallel with the telescope, are fixed two other instruments dedicated to solar observation :

  • A 90 mm coronograph for the observation of solar protuberances

  • A 60mm H alpha bezel for the observation of sun spots and all of the sun phenomena

 

Other instruments and mounts are present and available on request.

Adapter rings for cameras are available, so do not forget your camera bodies !

Many photographs made by us are visible in the gallery.
