| 説明 | The main dome houses the 40-inch diameter Great Refractor. Built in 1897, it's the largest refracting telescope in the world.To allow access to the eyepiece no matter the angle of the telescope, the whole floor can be raised and lowered, while the dome can be rotated to align the slit with the desired area of sky.Yerkes Observatory - Williams Bay, WI |
