在山顶上建造世界级的望远镜给天文台的创始人带来了许多挑战。崎岖的道路甚至更加粗糙的地形限制了进入山区。尽管如此,来自哈佛大学,南加州大学和卡内基机构的人才联盟也开始致力于建造天文台。新站点订购了两台望远镜,一台40英寸的Alvan Clark乐器和一台13英寸的折射镜。哈佛天文学家在19世纪80年代后期开始使用天文台。侵蚀游客和土地所有者使事情变得困难,有一段时间天文台网站关闭。计划中的40英寸望远镜被转移到伊利诺伊州的Yerkes天文台使用。最终,黑尔和其他人决定返回威尔逊山,在那里建造新的望远镜。作为天文学新进展的一部分,黑尔想要进行恒星光谱学研究。经过多次反复和谈判,黑尔签署了一份合同,在威尔逊山顶部租赁40英亩土地,建造一座天文台。特别是,他想在那里建立一个太阳观测站。花了几年时间,但最终,四座巨大的望远镜,包括世界上最大的太阳能和恒星仪器,将建在山上。利用这些设施,埃德温哈勃等天文学家对恒星和星系进行了重大发现

The construction of world-class telescopes on the top of the mountain brought many challenges to the founders of the Observatory. Rugged roads and even rougher terrain limit access to the mountains. Despite this, talent unions from Harvard University, the University of Southern California and Carnegie have also begun to build observatories. The new site ordered two telescopes, a 40-inch Alvan Clark instrument and a 13-inch refractor. Harvard astronomers began using the Observatory in the late 1880s. Erosion of tourists and landowners has made things difficult, and the Observatory website has been closed for some time. The planned 40-inch telescope was transferred to the Yerkes Observatory in Illinois. In the end, Hale and others decided to return to Mount Wilson to build a new telescope there. As part of a new advance in astronomy, Hale wants to conduct stellar spectroscopy. After repeated and repeated negotiations, Hale signed a contract to lease 40 acres of land at the top of Mount Wilson to build an observatory. In particular, he wanted to build a solar observatory there. It took a few years, but in the end, four huge telescopes, including the world’s largest solar and stellar instruments, will be built on the mountains. Using these facilities, astronomers such as Edwin Hubble made major discoveries about stars and galaxies.
