Paper Abstract

In this paper we want to contribute to steer the open, on going design debate of the Extremely Large Telescopes Adaptive Optics. We discuss first from the application point of view whether or not the very existence of ELT projects should be linked to the feasibility and demonstration of Multi-Conjugate AO. We show that ELT will justify their very existence also with scaled conventional AO, especially if inserted in a step-up plan to reach MCAO at a second stage. Then we layout a modular, hybrid AO system conceptual design, optimized for ELTs'. We discuss possible subsystems, expected performances and tradeoffs. The paper reports on research still in progress.
