A Very Wide-Field CCD Camera for Kiso Schmidt Telescope

A wide-field CCD camera has been manufactured for use on the 1.05m Schmidt telescope at Kiso Observatory. The camera makes use of a SiTe 2048 X 2048 CCD and has a wide field of view of 5 1 ' X 5 1' with a pixel resolution of I .5"/ pixel at the prime focus of the telescope. The backside-illuminated CCD allows us to observe from 3500 A to I ;Im. Fortunately, the shape of the CCD surface had a convex figure with very similar curvature to the focal plane of the Kiso Schmidt telescope, this coincidence helped us to avoid the field-flattener from the camera. Basic performances of the camera like the read-out noise were investigated.
