The objective is the acquisition of a large-format, ultraviolet- sensitive CCD and an appropriate set of image quality filters that will enhance and extend the imaging and spectroscopic capabilities of the Lowell Observatory. For direct imaging, the detector will provide a field of view sixteen times that of the largest available detector at a 1.07-m telescope in direct imaging mode. At the Perkins 1.8-m telescope the field size will initially be increased only slightly, but there will be an order-of-magnitude gain in UV sensitivity; increased coverage will be achieved when a planned focal reducer or Newtonian focus is implemented. By virtue of its increased areal and spectral coverage, the new CCD will allow Lowell Observatory staff and visitors to undertake research that cannot at present be attempted. Among the scientific goals are: studying the blue stellar content and the interstellar medium of galaxies, determining luminosity functions and dynamical properties of open clusters in our own Galaxy, investigating properties of the interstellar medium by means of high-resolution spectroscopy of early-type stars, investigating the large-scale comatic and tail structure of comets using narrowband photometry, enhancing the discovery rate of Earth-approaching asteroids and assessing their hazard to Earth, and searching effectively for Kuiper belt objects.

目的是获取大型，紫外线敏感的CCD和一组适当的图像质量过滤器，该过滤器将增强和扩展Lowell天文台的成像和光谱功能。 对于直接成像，检测器将在直接成像模式下提供16倍以1.07米望远镜的最大可用检测器的视野。 在珀金斯1.8米的望远镜上，最初只会稍微增加场的大小，但是紫外线灵敏度将有刻度的增长。当实施计划的焦点或牛顿焦点时，将实现覆盖范围。 由于其面积和光谱覆盖率的增加，新的CCD将使洛厄尔天文台的工作人员和访客能够进行目前无法尝试的研究。 科学目标包括：研究星系的蓝色恒星含量和星际介质，确定我们自己的星系中开放簇的光度函数和动力学特性，通过高分辨率光谱的高分辨率光谱进行早期型星星的高分辨率光谱，研究较大的尺度结构的compation-comeets commote commigation sappers sappers commigation commigation commigation commigation commoffice commigation commigation sappers roptry offers的高分辨率光谱，以研究星际介质的特性。小行星并评估它们对地球的危害，并有效地寻找柯伊伯带对象。
