Very dim galaxies challenge our understanding of how galaxies formed. Yet it is hard to study such galaxies using normal telescopes. The problem is that normal telescopes use a “secondary” mirror to bounce light from a “primary” mirror onto an eyepiece or a camera. This secondary mirror blocks the primary mirror and distorts the image. Here the investigators will use a new type of telescope that is made by combining several “refracting” telescopes to form one larger telescope. A refracting telescope does not require a secondary mirror. So, images from a refracting telescope are clearer than images from a normal telescope. This new telescope is designed to study very dim galaxies. The telescope will be used to study the Milky Way and other galaxies. The telescope will also be used to search for Earth-like planets orbiting white-dwarf stars. The telescope will also be used by educators and for public outreach. And the telescope will be used by faculty and students at historically black colleges and universities.Condor is the name for a set of six off-the-shelf refracting telescopes with six off-the-shelf CMOS cameras that form an array telescope. The investigators plan to locate the telescope initially in New Mexico fpr a Condor Northern Survey, then relocate to the Rio Hurtado Valley in Chile in June 2022 and initiate the Condor Southern Sky Survey. Condor is equipped with broad- and narrow-band filters and can acquire data at a cadence of 1 min. The science includes studying the incidence of very-low-surface- brightness galaxies and galaxy features across a variety of galaxy environments, and discovering transiting Earth-like planets in the habitable zones of white dwarfs. The project includes allocating 20% of the available observing time to a broader community that includes 10% of the total to investigators at historically black colleges and universities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非常暗淡的星系挑战了我们对星系如何形成的理解。 然而，用普通的望远镜很难研究这样的星系。 问题是，普通的望远镜使用“次”镜将“主”镜的光线反射到目镜或相机上。 此次镜像会阻挡主镜像并扭曲映像。 在这里，研究人员将使用一种新型的望远镜，它是由几个“折射”望远镜组合成一个更大的望远镜。 折射望远镜不需要副镜。 因此，折射望远镜的图像比普通望远镜的图像更清晰。 这架新望远镜是为研究非常暗淡的星系而设计的。 该望远镜将用于研究银河系和其他星系。 该望远镜还将用于搜索围绕白矮星运行的类地行星。 该望远镜还将被教育工作者和公众使用。 这架望远镜将被历史悠久的黑人学院和大学的教职员工和学生使用。Condor是一套六架现成的折射望远镜的名称，其中六架现成的CMOS相机组成了一个阵列望远镜。 研究人员计划将望远镜最初定位在新墨西哥州，进行秃鹰北方巡天，然后于2022年6月搬迁到智利的里奥乌尔塔多山谷，并启动秃鹰南方巡天。 Condor配备了宽带和窄带滤波器，可以以1分钟的节奏获取数据。科学研究包括研究极低表面亮度星系的发生率和各种星系环境中的星系特征，以及在白色矮星的可居住区发现凌日类地行星。 该项目包括将20%的可用观察时间分配给更广泛的社区，其中10%的时间分配给历史悠久的黑人学院和大学的研究人员。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
