Rendering of the E-ELT telescope structure inside its enclosure. The 39-metre primary mirror reflects the light first to the 4.2-metre secondary mirror hanging upside-down at 60m height. The light is then further transmitted to mirrors 3, 4 and 5 (located in the central tower) and finally reflected to either side where the astronomical cameras sitting on the Nasmyth platforms will see nearly perfect images of the celestial objects. To assist the adaptive optics included in the telescope, telescope guide stars are created in the sky by using powerful lasers launched at the corners of the primary mirror cell.
The design for the E-ELT shown here was published in 2009 and is preliminary.Credit:
