【摘要】@@ The integration testing of 4K×4K Charge Coupled Device (CCD) detection system developed by researchers from the CAS Purple Mountain Observatory in cooperation with overseas coworkers was successfully carried out for the Schmidt telescope at the Xuyi station in east China's Jiangsu Province recently.Preliminary observations have led to exciting results. From the CCD image with an exposure time of 1 sec, 18th magnitude stars are clearly detectable while in the CCD image with an exposure time of 20sec, 21.2th magnitude stars are recognizable. 【总页数】1页(202) 【关键词】 【作者】佚名 【作者单位】无 【正文语种】中文 【中图分类】 【相关文献】
