Antilhue - Chile

Home Latest Results Observatory Gallery Technical Notes The Author - Contact Copyright Info Site Map



The Antilhue observatory is located about 100km (60 miles) north of Santiago de Chile, in a valley in the foothills of the Cordillera de los Andes, the Andes mountain range.

Altitude is 1500 m above msl  (4500 ft). Because of the observatory's valley location there are hills and mountains all around, resulting in a 360 horizon at 10-15 elevation.

It is a dark site, with some interference from the city of Los Andes to the south.  Since southern objects always culminate above the pole at some time of the year, they can be observed and imaged at a high enough elevation above the horizon.

The area can best be described as semi-desert. There is only limited tree growth.  Bushes and cactus of the Echinopsis Chiloensis type abound.



It has dry, hot summers with generally clear, albeit somewhat hazy night skies from October thru March. Winters are wet and mostly cloudy, with frequent intervals of very transparent skies, usually after a cold front has moved through.
