An unconventional, highly sensitive camera system is described, suitable for silicon or amplified silicon (SIT or EBS) vidicons. Features are a variable field size and sweep rate and a low-noise video amplifier. Used on a 91-cm telescope, it can detect 15th magnitude stars with the silicon vidicon. With an SIT tube, the limit is 17 on the 91-cm and 20.5 on the 4-m telescope. The system is briefly compared with an I-SIT camera.
描述了一种非常规的、高灵敏度的相机系统,适用于硅靶或增强硅靶(SIT或EBS)视像管。其特点是可变视场大小和扫描速率以及低噪声视频放大器。用在一台91厘米望远镜上,使用硅靶视像管时它能探测到15等星。使用SIT管时,在91厘米望远镜上极限星等为17等,在4米望远镜上为20.5等。该系统与一台I-SIT相机进行了简要比较。
