雨云过后，利克天文台36英寸大折射望远镜的圆顶于11月19日开放。这架历史悠久的望远镜对准了月偏食的月球。为了保持天文学家的夜视能力，在昏暗的红色灯光下，望远镜控制装置、座标刻度盘和折射望远镜57英尺长的筒体被捕捉到这张高动态范围的照片中。从缩短的桶状和穹状缝隙中可以看到，在几乎完全的月食阶段之后，月亮盘变得更加明亮，在徘徊的云层中形成了一个彩色的日冕。从开放的圆顶上，可以看到头顶上晴朗的天空，昴宿星团距离月球和地球的阴影约5度。值得注意的APOD提交：2021年11月19日的月食

Rain clouds passed and the dome of the Lick Observatory's 36 inch Great Refractor opened on November 19. The historic telescope was pointed toward a partially eclipsed Moon. Illuminated by dim red lighting to preserve an astronomer's night vision, telescope controls, coordinate dials, and the refractor's 57 foot long barrel were captured in this high dynamic range image. Visible beyond the foreshortened barrel and dome slit, growing brighter after its almost total eclipse phase, the lunar disk created a colorful corona through lingering clouds. From the open dome, the view of the clearing sky above includes the Pleiades star cluster about 5 degrees from Moon and Earth's shadow. Notable APOD Submissions: Lunar Eclipse of 2021 November 19
