ELT - Where the Secondary Mirror Becomes a Giant
Abstract
The Extremely Large Telescope (ELT) is at the core of ESO's vision to deliver the largest optical and infrared telescope in the world. Following on from our previous Messenger article describing the primary mirror (M1), here we focus on the secondary (M2) and the tertiary (M3) mirrors of the ELT, outlining the complexity and challenges involved, and the current manufacturing status.
