威尔逊山望远镜是建造和运输山峰的庞然大物。由于很少有车辆可以驾驶，因此黑尔不得不依靠马拉车来提升所需的后视镜和设备。所有艰苦工作的结果是建造了Snow Solar望远镜，这是第一个安装在山上的望远镜。加入它是60英尺的太阳能塔，然后是一个150英尺的太阳能塔。对于非太阳能观测，天文台建造了60英寸的Hale望远镜，最后是100英寸的Hooker望远镜。 Hooker多年来一直保持着世界上最大的望远镜的记录，直到在Palomar建造了200英寸的望远镜。威尔逊山天文台多年来最终获得了几台太阳望远镜。它还增加了红外空间干涉仪等仪器。该阵列为天文学家提供了另一种研究天体红外辐射的方法。此外，还有两个恒星干涉仪，一个61厘米的望远镜，以及加州理工学院的红外望远镜也在山上使用。 2004年，佐治亚州立大学建立了一个名为CHARA阵列的光学干涉仪（以角分辨率天文学中心命名）。它是同类中最强大的乐器之一。

The Mount Wilson Telescope is a behemoth that builds and transports mountain peaks. Since few vehicles can drive, Hale has to rely on horse-drawn carriages to upgrade the required mirrors and equipment. The result of all the hard work was the construction of the Snow Solar telescope, the first telescope installed on the mountain. Join it with a 60-foot solar tower and then a 150-foot solar tower. For non-solar observations, the Observatory built the 60-inch Hale telescope and finally the 100-inch Hooker telescope. Hooker has maintained the record of the world’s largest telescope for many years until a 200-inch telescope was built in Palomar. The Mount Wilson Observatory has finally acquired several solar telescopes over the years. It also adds instruments such as infrared space interferometers. The array provides astronomers with another way to study celestial infrared radiation. In addition, there are two stellar interferometers, a 61-cm telescope, and the California Institute of Technology’s infrared telescope, which is also used on the mountain. In 2004, Georgia State University established an optical interferometer called the CHARA array (named after the Center for Angular Resolution). It is one of the most powerful instruments of its kind.
