Small DC motors follow the stars at minus 84 degrees.
The maxon DC motor powered Dome C telescope in the Antarctic is constantly in use under some of the harshest weather conditions on Earth.
The Concordia Station (known as Dome C) research station lies in Eastern Antarctica at 3.2km above sea level, one of the coldest places on Earth. In temperatures of down to minus 84 degrees the University of Nice’s Astrophysics Laboratory (LUAN) telescope has been in constant use in this inhospitable place 24 hours a day, 7 days a week.
