The highest resolution images of faint targets ever taken in the visible or near infrared were obtained by combining Lucky Imaging with low order adaptive optics. This proposal is to develop further the technologies needed for an innovative approach to wavefront sensing that will allow dramatically fainter reference stars to be used than with conventional Shack-Hartmann sensors. These will be incorporated in an instrument to be used initially on the WHT 4.2 m with the potential to move to the GTC 10 meter telescope on La Palma. Using only faint natural guide stars, angular resolution as good as 15 milliarcseconds in the GTC and 40 milliarcseconds on the WHT in I-band will be obtained over a substantial fraction of the northern sky. The instrument is part of a collaboration led by the Institute of Astronomy of the University of Cambridge, with the IAC (La Laguna), UPCT (Cartagena), University of Cologne and the staff of the ING (La Palma). This project is central to the aims and aspirations of the STFC science program for astronomy. It also supports the strongly expressed wish to integrate activities of the ING with those of the IAC/GranteCan telescope on La Palma. The project builds on several exciting new technologies that have made great strides over the last year in Cambridge. In particular, much higher selection percentages are now achieved without loss of resolution. The instrument proposed here will start as a visitor instrument permanently resident on the island, with the medium-term goal of transitioning to a common user facility for use on the two La Palma telescopes. The instrument first light on the WHT will be ~18 months after kick-off and fully operational by the end of 3 years. The costs will be shared between the UK and collaborators in Spain and Germany. This proposal is for a total of £138K from STFC (£167K FEC) including components, travel and salaries. The entire project is expected to cost in the region of £1.5 million.

通过将瑞幸成像与低阶自适应光学相结合，获得了有史以来在可见光或近红外拍摄的最高分辨率的微弱目标图像。这项提议是为了进一步开发一种创新的波前探测方法所需的技术，这种方法将允许使用比传统的夏克-哈特曼传感器明显更暗的参考星。这些将被合并到最初用于WHT 4.2米的仪器中，并有可能转移到拉帕尔马上的GTC 10米望远镜。仅使用微弱的自然导航星，就可以在北部天空的大部分区域获得高达15毫角秒的GTC和40毫角秒的WHT的角分辨率。该仪器是由剑桥大学天文研究所与IAC(拉拉古纳)、UPCT(卡塔赫纳)、科隆大学和ING(拉帕尔马)工作人员领导的合作的一部分。该项目是STFC天文学科学计划目标和抱负的核心。它还支持ING表示的将其活动与拉帕尔马上IAC/GranTeCan望远镜的活动相结合的强烈愿望。该项目建立在几项令人兴奋的新技术的基础上，这些技术在过去一年里在剑桥取得了长足的进步。特别是，现在在不损失分辨率的情况下实现了更高的选择百分比。这里提议的仪器将作为一个常驻在岛上的访客仪器开始，中期目标是过渡到一个共同的用户设施，供两个拉帕尔马望远镜使用。该仪器在WHT上的第一次亮光将在启动后约18个月，并在3年结束时完全运行。费用将由英国以及西班牙和德国的合作者分担。这份提案是从STFC(GB 167K FEC)获得的总计GB 138K，包括零部件、差旅和工资。整个项目预计耗资约150万GB。
