The ESO Very Large Telescope consists of an array of four 8-meter telescopes which can work independently or in combined mode. ... In such a mount the telescope tube moves around a horizontal axis called elevation axis. ... The telescope tube itself consists of a steel structure supporting at the bottom the primary mirror (M1) in its cell, and at the top the M2 Unit by means of metallic beams called "spiders". ... The VLT can operate in either Cassegrain, Nasmyth or Coud focus. ...
