Abstract

Performing Adaptive Optics on a 100m scale is not only a formidable enginnering goal for nowadays. It requires also to look for ideas, concepts, and ways of sorting out technicalities, that are beyond the current visions about Adaptive Optics aboard 8..10m class telescopes. Different physical regimes require to have different metrics when weighting pros and cons of one approach with respect to another. My current, and maybe very personal view, is here exposed, along with the reasons why I think one should face such a target recalling in his mind that the solution can comes together with options that can look irrespective of apparently well established configurations. Substantially, a road--map including Laser Guide Stars whose light is treated as it is the Natural Guide Stars one, is sketched.
