2. MONSOON Image Acquisition System Peter Moore (1) and Gustavo Rahmer (2) (1) National Optical Astronomy Observatory (2) Cerro Tololo Inter-American Observatory “Rain drops keep falling on our heads” The MONSOON development program continues and we report on the current status of, and the future plans for this project. The Forecast : Warm deluges of success with some cold showers of reality

3. Taking a photon shower Not enough time to catch all the photons we need ! Big instruments – Big focal planes More photons !! UV – VIS – NIR – MIR. MONSOON designed to accommodate these requirements So; where is MONSOON ?
