Altair is the adaptive optics system developed by NRC Canada for the Gemini North Telescope. Altair uses modal control and a quad-cell based Shack-Hartmann wavefront sensor. In order for Altair to adapt to changes in the observing conditions, two optimizers are activated when the AO loop is closed. These optimizers are the modal gain optimizer (MGO) and the centroid gain optimizer (CGO). This paper discusses the implementation and timing results of these optimizers.
