Installation of Motors Begins on VLT Unit Telescope 1 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.

(Photo obtained on September 15, 1997). |  ESO Press Photo 27b/97 [JPG, 161k] : Looking out through the dome slit over the UT1 with the top ring and spider in place. The building to the left is the Interferometric Laboratory. (Photo obtained on September 15, 1997). | |  ESO Press Photo 27c/97 [JPG, 111k] : One of the two large altitude bearings on the UT1. When completed, the light collected by the telescope will pass through the opening to one of the instruments at the Nasmyth platform. Beyond the bearing is seen the massive centre piece, which supports the tube structure and the 9-m top ring. (Photo obtained on September 19, 1997). |  ESO Press Photo 27d/97 [JPG, 149k] : Same area of the telescope, but seen more from the side. (Photo obtained on September 17, 1997). | |  ESO Press Photo 27e/97 [JPG, 148k] : The roof is now in place on the Control Building that is located further down the mountain side. View from Unit Telescope 1. (Photo obtained on September 17, 1997). |  ESO Press Photo 27f/97 [JPG, 156k] : Inside the Control Building. From here, the astronomers and night assistants will control the Very Large Telescope and receive the raw data from the many instruments. (Photo obtained on September 19, 1997). |
