  We developed game-changing concepts for meter(s) class very-wide-field
telescopes, spanning three orders of magnitude of the covered field of view.
Multiple cameras and monocentric systems: from the Smart Fast Cameras (with a
quasi-monocentric aperture), through the FlyEye, toward a MezzoCielo concept
(both with a truly monocentric aperture). MezzoCielo (or "half of the sky") is
the last developed concept for a new class of telescopes. Such a concept is
based on a fully spherical optical surface filled with a low refractive index,
and high transparency liquid surrounded by multiple identical cameras.
MezzoCielo is capable to reach field of views in the range of ten to twenty
thousand square degrees.
