This innocent magic, the fruit at the same time of child-like musings and of manly genius -- this patient untiring labour, of which Boxtel knew himself to be incapable -- made him, gnawed as he was with envy, centre all his life, all his thoughts, and all his hopes in his telescope.
Sometimes, whilst covering Van Baerle with his telescope, he deluded himself into a belief that he was levelling a never-failing musket at him; and then he would seek with his finger for the trigger to fire the shot which was to have killed his neighbour.

NASA released a time lapse of workers (video below) preparing the James Webb Space Telescope
and rolling it into the cryochamber at Houston's Johnson Space Center, where it was (http://www.ibtimes.com/watch-nasa-deep-freeze-its-alien-hunting-telescope-test-2571029) chilling for a few months , including (http://www.ibtimes.com/nasas-alien-hunting-telescope-rides-out-hurricane-harvey-houston-2583906) as Hurricane Harvey pounded Texas .
The Arecibo Observatory (305 m), for instance, recently ceded the distinction of world's largest single-dish radio telescope
to China's Five-hundred-meter Aperture Spherical Radio Telescope
, or FAST (500 m).
Incorporating a prism within the telescope
adds weight and depending upon the type of prism or prism system used will impact upon the physical design of the telescope
and image quality.
adding to the venture includes the South Pole Telescope
in Antarctica, the James Clerk Maxwell Telescope
in Hawaii, and the Atacama Cosmology Telescope
in the desert of northern Chile.
