CANARY is the multi-object adaptive optics (MOAO) pathfinder for the multi object IR spectrometer EAGLE proposed on the European Extremely Large Telescope (E-ELT). CANARY was installed in September 2010 on the William Herschel Telescope (WHT) Canary Islands, Spain. For the first time, MOAO correction has been demonstrated using 3 widely separated off-axis natural guide stars and one deformable mirror in open loop in a target direction. We present the detailed analysis of the fourth night...
