MAGIQ at the W. M. Keck Observatory: initial deployment of a new acquisition, guiding, and image quality monitoring system

The W. M. Keck Observatoryhas completed the development and initial deployment of MAGIQ, the Multi-function Acquisition, Guiding and Image Qualitymonitoring system. MAGIQ is an integrated system for acquisition, guiding and image qualitymeasurement for the Keck telescopes. This system replaces the acquisition and guiding hardware and software for existing instruments at the Observatoryand is now the standard for visible wavelength band acquisition cameras for future instrumentation. In this paper we report on the final design and implementation of this new system, which includes three major components: a visible wavelength band acquisition camera, image qualitymeasurement capability, and software for acquisition, guiding and image qualitymonitoring. The overall performance is described, as well as the details of our approach to integrating low order wavefront sensing capability in order to provide closed loop control of telescope focus.
