The CFHT Open Cluster Survey

Much of the existing data for Galactic open clusters dates back to photographic observations which are not as deep nor as precise as can be obtained with modern CCD detectors. With the development of large mosaic CCD cameras, such as the 12k x 8k imager at CFHT which covers about a third of a square degree on the sky, a major drawback to using CCDs for open cluster work (the small field of view with single CCD chips) has been solved. We will present a few images obtained thus far in this project and some results for NGC 2099, the first cluster analyzed in some detail.
