Raven soars through first light and second run
Raven, a Multi-Object Adaptive Optics (MOAO) science demonstrator, successfully saw first light at the Subaru Telescope on the nights of May 13 and 14, 2014 and completed its second run during the nights of August 9 and 10, 2014. Developed by the Adaptive Optics Lab of the University of Victoria (UVic) in partnership with the National Astronomical Observatory of Japan (NAOJ), the National Research Council of Canada (NRC Herzberg), and Tohoku University, Raven is the first MOAO science and technical demonstrator to be installed and tested on an 8 m class telescope. It marks a technological advance in the number of science targets available for adaptive optics; it uses measurements from multiple guide stars to provide corrections for atmospheric turbulence in any locations of the field of view of the telescope.
