| 説明 | Paris, FranceThe Sorbonne University built the tower on its Paris campus to house an astronomical observatory for its students. The structure was erected during the reconstruction of the Sorbonne, between 1885 and 1901.[1] The tower is 39 meters high, has an upper and lower dome, and includes several rooms. The upper dome houses the telescope, and the lower dome contains an optics workshop for amateurs to make mirrors (previously, a meridian circle was installed in that space). The tower is operated by the Société astronomique de France and is available for tours and amateur observations.In 1980, an equatorial mount refracting telescope of 153 mm diameter and 2,300 mm focal length was installed in the upper dome. The telescope is owned by the Société astronomique de France. It was built in 1935 and was originally installed in the Observatory of the rue Serpente on top of the society’s former headquarters at 28, rue Serpente, Paris.en.wikipedia.org/wiki/Astronomy_Tower_of_the_Sorbonne |
