The New Telescopes,more than cancelled out by increased problems of atmospheric turbulence. Certainly the next giant instrument was not a success. In 1976 the Russians set up a 236-inch reflector at Mount Pastukhov, in the Caucasus region, and great things were expected of it.

Mitsuo Gen,David Green,Byoung-Tak Zhang. telescopes may have been low-powered, and by modern standards inefficient, but they were at least manageable. This was emphatically not true of the best refractors of the later seventeenth century, which were so incredibly awkward that one wonders how they can ever have been used successfully.

Before the Telescope, Today we can probe far into the universe, and study objects which are so far away that we see them as they used to be before the Earth or even the Sun came into existence; yet the story of telescopic astronomy extends back for only a few hundred years.

Thomas Harriot, one-time tutor to Sir Walter Raleigh, drew a telescopic map of the Moon months before Galileo made his original telescope. It may well be that the first statement is also wrong, and t

Enter the Reflector,ake mistakes, and one of these concerned the refracting telescope. He could see no way of overcoming the false colour problem, so that in his view the refractor could never be developed to any great extent. Therefore, he adopted a completely different system. Why not dispense with the object-glass a
