The mount was developed by Joseph von Fraunhofer for the Great Dorpat Refractor<ref>{{cite book |url=https://archive.org/details/fireflyastronomy00wood |url-access=registration |page=[https://archive.org/details/fireflyastronomy00wood/page/71 71] |title=Firefly Astronomy Dictionary |publisher=Firefly Books Ltd. 2003 }}</ref> that was finished in 1824. The telescope is placed on one end of the declination axis (top left in image), and a suitable counterweight on other end of it (bottom right). The right ascension axis has bearings below the T-joint, that is, it is not supported above the declination axis.
