A Franco-British team has demonstrated for the first time on-sky the feasibility of
so-called Multi-Object Adaptive Optics (MOAO). MOAO provides the high spatial resolution delivered by current
adaptive-optics systems, but over a much larger field of view, allowing many objects to be observed simultaneously.
The demonstration was made with the purpose-built CANARY instrument installed at the Nasmyth focus of the William Herschel Telescope on La Palma. Analysis of the
first results obtained in September 2010 shows that CANARY delivered the expected performance the first time it was used - a spectacular success.
