Until it is removed or corrected, the distant nebulae a billion or so light-years away will keep their privacy...
...mirror is 24 inches thick at the edge, and looks absolutely rigid. But, judged by the delicate standards of astronomy, it is almost as flexible as cellophane, changing its shape appreciably (in millionths of an inch) with each new position as the telescope swings with the stars. In cells on the under side of the mirror (see cut) are 36 complicated mechanisms, each with 1,100 parts, designed to control this out-of-focus warping by varying pressure...
