ELT in its enclosure

June 2009 version of the design of the 40-metre-class Extremely Large Telescope (ELT) in its enclosure, currently being planned by ESO (artist’s impression). The ELT will be mounted on a central concrete pier. It will be shielded from the wind by a dome enclosure. This dome will have an approximate height of 80m and a footprint of about 100m diameter.

The design for the ELT shown here is preliminary.
