Installation of Motors Begins on VLT Unit Telescope 1
22 September 1997
With the completed assembly of the heavy parts that form the mechanical structure of the first (UT1) of the four large VLT Unit Telescopes, the integration of the motor that will move the telescope around the (horizontal) altitude axis is now about to start.
The next step will be the integration of the encoders which will read the precise position of the upper part of the telescope (the `tube'). Thereafter follows the integration of the adaptor-rotator unit which will include the key elements of the adaptive optics.
In addition to the photos of the large altitude bearing and the shaft where the direct motor drive will be installed, this series also contains two views of the UT1 in its enclosure following the removal of the scaffolding needed for the mechanical assembly, as also two of the control building.
