From the very early concept presented in 2001 to the rst on-sky Multi-Object Adaptive Optics (MOAO) prototype system, exactly 10 years have elapsed. End of 2010, the pathnder instrument called CANARY obtained the rst open-loop, tomographically MOAO compensated images on the WHT. What were the challenges and what was demonstrated? What will be the future steps for a real astronomical MOAO system to be installed on an extremely large telescope (ELT)? We present the Canary...
