Vacuum Tower Telescope
It was built between 1983 and 1986, with first light in 1988.[3] It has a 70-centimetre (28-inch) diameter primary mirror and a focal length of 46 metres (151 ft). Thanks to an adaptive optics system KAOS (Kiepenheuer-institute Adaptive Optic System), in operation since spring 2000,[4][5] it is able to resolve details down to 0.2 arc seconds (150 km) on the Sun's surface.[6][7][8]
