Paper Abstract

We developed a new CCD readout system for the Kanata 1.5m telescope in Higashi-Hiroshima Astronomical Observatory, Hiroshima University, Japan, based on the system originally developed by the Kiso Array Controller (KAC) project. In this development we aim at reducing the size and the cost of the system. The system consists of CCD drive circuit, three-order low-pass filters, differential input A/D converter, FPGA, LVDC board, and can be operated by Linux host. We report the current design and performances of this system, and the future work as well. This readout system will be easily applicable to many other astronomical instruments.
