Great Refractor and Lunar Eclipse

Explanation: 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 halo 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.

说明: 11月19日,在降雨云通过之后,里克天文台0.91公尺口径大折射镜的圆顶开启。其内,这部颇具历史的望远镜则指向偏食月。这幅高动态范围影像,清楚记录了用以保持天文学家夜间视力的昏暗泛红照明灯光、望远镜控制器、座标旋钮和将近17.4公尺长的镜筒。在因透视缩短的镜筒和圆顶开口之后方,有接近月全食的食甚阶段后,逐渐变亮的月盘及残存薄云造成的多彩月晕。此外,在圆顶开口上方逐渐转晴的天空中,还有与月亮及地球影子相隔约5度的昴宿星团。
