Remarkably, even without the benefit of telescopes and other instruments that were being developed in Europe, this observatory provided detailed and reasonably accurate information about the celestial bodies.
On tähelepanuväärne, et ehkki selles observatooriumis polnud Euroopas leiutatud teleskoope ja muid instrumente, saadi seal hankida taevakehade kohta üksikasjalikku ja võrdlemisi täpset infot.
