Abstract : We present in this paper the very first on-sky results of full Multi-Object Adaptive Optics (MOAO) LQG control (i.e. all modes, with coupling, controlled with an LQG regulator), obtained in Spring 2013 on the CANARY demonstrator at the William Herschel Telescope (La Palma, Spain). The MOAO on-sky pathfinder CANARY features two AO configurations that have both been tested: single-conjugated AO and multi-object AO with NGS and NGS+LGS, together with vibration mitigation on tip and tilt modes. The successful MOAO results are presented and shortly analyzed in terms of performance and tuning.
