AO4ELT7 - General description

One of the major challenges that faces the future extremely large aperture telescopes (ELTs) is adaptive optics, and the goal of this conference is to gather specialists to review and discuss the latest developments in this field.

The topics of the conference include ELT's current design in terms of AO systems, related instruments and science goals, and also pathfinder projects planned or implemented on existing telescopes, including solar telescopes, which provide relevant results for the next ELT's design phase.
