This project involves the usage of new scientific CMOS (sCMOS) cameras produced by Andor for high-precision astronomical photometry. sCMOS cameras have recently been tested under laboratory conditions, and the results are extremely promising for astronomical purposes (Karpov et al., 2019). The Next Generation Transit Survey (NGTS; Wheatley et al., 2018) facility is a set of 12 identical 20cm telescopes situated at Paranal Observatory in Chile (one of the best sites in the world). NGTS surveys bright stars with high precision photometry in order to detect transiting "exoplanets" - planets orbiting other stars (e.g. NGTS-1b; Bayliss et al., 2018). We propose to couple a new generation Andor sCMOS detector to an NGTS telescope. The primary goal is, for the first time ever, to obtain high precision photometry of bright stars to detect transiting exoplanets. We will run this experiment alongside another NGTS telescope with an existing CCD camera for comparative purposes. sCMOS detectors have yet to be embraced by the astronomical community, however peer-reviewed publications of in-depth and meaningful on-sky assessments are the key to unlocking such acceptance.

该项目涉及使用Andor生产的新型科学CMOS（sCMOS）相机进行高精度天文光度测量。 sCMOS 相机最近在实验室条件下进行了测试，其结果对于天文用途来说非常有希望（Karpov 等人，2019）。下一代凌日巡天（NGTS；Wheatley 等人，2018）设施是一组 12 台相同的 20 厘米望远镜，位于智利帕拉纳尔天文台（世界上最好的地点之一）。 NGTS 通过高精度光度测量来勘测明亮恒星，以探测凌日“系外行星”——绕其他恒星运行的行星（例如 NGTS-1b；Bayliss 等人，2018）。我们建议将新一代 Andor sCMOS 探测器与 NGTS 望远镜耦合。主要目标是有史以来第一次获得明亮恒星的高精度光度测量，以探测凌日系外行星。我们将与另一台配备现有 CCD 相机的 NGTS 望远镜一起运行此实验，以进行比较。 sCMOS 探测器尚未得到天文学界的认可，但同行评审的深入且有意义的天空评估出版物是获得这种认可的关键。
