Scientific paper

We report results of laboratory and on-sky testing at Lick Observatory of a camera utilizing the Foveon F13 CMOS sensor. The CMOS Prototype #0 Camera (C3P0Cam) produces simultaneous images in 3 colors on short (20ms subrastered to 0.2s full-frame) timescales. We have verified 1-2% level photometric accuracy for time variable objects at V 14 Mag. We discuss the device quantum efficiency and noise properties as well as the relation between the three C3P0Cam colors and standard photometric bands. We discuss novel software which exploits the non-destructive readout for the F13 to generate very broad effective-dynamic-range images (>10^6) not affected by blooming near bright sources.
