Jay Baum Rich望远镜：智者天文台的百夫长28
The Jay Baum Rich telescope: a Centurion 28 at the Wise Observatory
摘要：
我们描述了智者天文台的第三台望远镜，一台安装于2013年的0.70米Centurion 28（C28 IL），并命名为Jay Baum Rich望远镜，以显着提高天文台的宽视场成像可能性。该望远镜从一个直径为5.5米的圆顶上运行，并配备了一个大幅面的红敏CCD相机，提供一个~ 1平方度的成像场，采样率为0”.83/像素。购置该望远镜是为了替代现有的1米望远镜，用于微透镜、凌日系外行星的光度测定、超新星和其他光学瞬变的跟踪以及星系周围极低表面亮度扩展特征的探测等研究。C28 IL的操作是机器人式的，只需要创建一个夜间观测计划，在下午观测之前加载。整个设施的组件和基础设施成本远低于30万美元，劳动力投资约为2人年。C28 IL的成功实施，以合理的成本，证明了小型望远镜在巨大的光收集器时代的可行性。
英文摘要：
We describe the third telescope of the Wise Observatory, a 0.70-m Centurion 28 (C28IL) installed in 2013 and named the Jay Baum Rich telescope to enhance significantly the wide-field imaging possibilities of the observatory. The telescope operates from a 5.5-m diameter dome and is equipped with a large-format red-sensitive CCD camera, offering a ~one square degree imaged field sampled at 0".83/pixel. The telescope was acquired to provide an alternative to the existing 1-m telescope for studies such as microlensing, photometry of transiting exo-planets, the follow-up of supernovae and other optical transients, and the detection of very low surface brightness extended features around galaxies. The operation of the C28IL is robotic, requiring only the creation of a night observing plan that is loaded in the afternoon prior to the observations. The entire facility was erected for a component and infrastructure cost of well under 300k$ and a labor investment of about two person-year. The successful implementation of the C28IL, at a reasonable cost, demonstrates the viability of small telescopes in an age of huge light-collectors.
