Description: Thycho Brahe made celestial globe in 1580s. About 1.6 meter in radius,took over 10 years to make. Most of the work involved making the hollow wooden globe as perfectly spherical as possible, after which it was covered in brass plates. The globe had two primary scientific uses: to record the position of stars observed by Tycho. By 1595 he had 1000 accurately observed stars inscribed on the globe. However, it was originally intended as a computational device. By means of auxiliary circles, the local azimuth/ altitude coordinates, as measured with Tycho’s instruments, were converted into the conventional celestial coordinates used to record stellar and planetary positions.
