木曾天文台的1.05米施密特望远镜已经制造了一台宽视场CCD照相机。该相机使用SiTe 2048 X 2048 CCD，在望远镜的主焦点处具有51 ' X 51'的宽视场和1.5”/像素的像素分辨率。背照式CCD允许我们从3500 A到I ;Im进行观察。幸运的是，CCD表面的形状具有与木曾施密特望远镜的焦平面非常相似的曲率的凸形，这种巧合帮助我们避免了来自相机的场干扰。研究了摄像机的基本性能，如读出噪声。
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.
