Abstract
An ultra-high-sensitivity HDTV color camera has been developed using 3 proximity focused image intensifier tubes of large image size(useful area 40 mm DIA.) and 3 FIT CCDs of 2/3-inch 2M-pixels. It has a high sensitivity of 3000 times as same as conventional HDTV CCD cameras. It makes possible to shoot high-quality realtime-images of meteor nebulae and galaxies.
