弗雷娅·奥尔德雷德，那里的一名本科生。建造一个完全由学生设计和运行的射电望远镜的愿景很快激发了一个小型但专注的团队。资助这样一个雄心勃勃的事业是第一个挑战，这是由埃克塞特校友基金和研究理事会英国催化剂种子基金，我们对此表示感谢大学的资金解决。下一个最紧迫的问题是找到望远镜的位置。起初，我们和大学校园服务团队认为，把这道菜放在校园里是一个现实的可能性，但我们很快发现，没有足够的空间。接下来，我们试图把望远镜放在国家天文台，但规划限制阻碍了我们的道路。然后，我们试图把网撒得更远，但每一条路都是死路。经过几个月越来越疯狂的寻找，望远镜终于在康沃尔郡利斯卡德以南的卡拉登天文台找到了家。这个天文台是退休核工程师和业主肯班尼特和他的妻子穆里尔班尼特的激情项目。他们坚信科学、技术、工程和数学学科的重要性，以及公众的广泛参与，他们花了10年时间将一个废弃的养猪场改造成了一个尖端的光学天文台。他们对天文学是如此的投入，以至于他们和康沃尔理事会一起沿着，一直是为博德明摩尔赢得黑暗天空景观分类运动背后的驱动力。这一分类不仅有很强的商业案例-从康沃尔郡蓬勃发展的航空航天和深空通信产业吸引了来自四面八方的天文旅游-但科学案例同样引人注目，为未来几代人保留了该地区原始的黑暗天空。当我们向肯提出将望远镜安置在卡拉登的想法时，他
Freya Aldred, an undergraduate there. The vision of constructing an entirely student-designed and run radio telescope quickly inspired a small but devoted team. Financing such an ambitious undertaking was the first challenge, which was resolved by funding from the University of Exeter Alumni Fund and the Research Councils UK Catalyst Seed Fund, for which we are grateful. The next most pressing issue was finding a location for the telescope. At first, we and the university campus services team thought that situating the dish on campus would be a realistic possibility, but we soon found that there was not enough space. Next, we tried to put the telescope at the NLO, but planning constraints stood in our path. We then tried casting the net further afield, but every avenue turned out to be a dead end.After months of increasingly frantic searching, the telescope finally found a home at Caradon Observatory, just south of Liskeard in Cornwall. This observatory is the passion project of retired nuclear engineer and owner Ken Bennett and his wife Muriel Bennett. They have a staunch belief in the importance of the STEM subjects and public outreach–and a disused pig farm which thay have spent the past 10 years converting into a cutting-edge optical observatory. So devoted are they to astronomy that they, along with Cornwall Council, have been the driving forces behind the campaign to earn the classification of Dark Sky Landscape for Bodmin Moor. Not only does this classification have a strong business case–from the burgeoning aerospace and deep space communications industry in Cornwall attracting astro tourism from far and wide–but the science case is equally compelling, preserving the pristine dark skies in the area for generations to come. When we approached Ken with the idea of situating our telescope at Caradon, he
