1200 nights and counting: Queued Service Observing at CFHT
P. Martin (+ QSO Team)

Abstract: Since 2001, all the wide-field cameras at CFHT are operated under a highly efficient and flexible Queued Service Observing (QSO) mode. The presentation will review the lessons learned from queue observing with CFH12K, MegaCam and WIRCam, for more than 1200 nights so far. Operations, phase 2s, statistics, efficiencies, challenges, etc. will all be briefly described as well as ongoing plans to integrate the spectropolarimeter ESPaDOnS within QSO in 2008.
