Model of 200-Inch Telescope to be Displayed

From Horology magazine, July 1938


The planets, moon and stars, will be brought "down to earth" at the 1939 Golden Gate International Exposition on San Francisco Bay.

To the edification of millions of visitors to the Hall of Science at the $50,000,000 World's Fair of the West, the whole galaxy of the universe will be brought down to the level of the human eye by means of a vast astronomical exhibit planned by the University of California.

Center of the display, which will be a part of the University's $1,500,000 array of exhibits, will be a model of the 700ton telescope now being installed on Mount Palomar in Southern California.  It will be built exactly to scale, with the 200-inch mirror being duplicated by an eight-inch facsimile, and every other feature being faithfully reproduced in proportion.

The telescope will be flanked on either side by a series of transparencies giving close-ups of the planets and other heavenly bodies. One panel will show the moon as if it were brought within 24 miles of the earth. Other panels will show the relation of time to the planets and still another set of transparencies will show the relation of astronomical bodies to everyday human life.

When completed, the Mount Palomar telescope is expected to open new lines of exploration in the universe. The Exposition model will show exactly how this is to be done, at least a year before it is actually accomplished.
