"Multi-conjugate Adaptive Optics: first results on the sky"

Herve Bouy, UC Berkeley

The first astronomical MCAO instrument has recently been brought up on
the sky at the Very Large Telecope in Chile and successfully performed
three observing runs, providing high spatial resolution over an
unprecedented wide field (1'x1').  I will briefly present the
performances and results obtained with this prototype instrument, and
discuss them in the context for future astronomical instrumentation.
