The polar axis is of steel,
12 inches in diameter, 10 feet long. The declination axis is also of steel, is 10 inches in diameter, 10 feet long. The tube is of steel, 57 feet long. Its diameter is 4 feet at the center, tapering toward each end to 38 inches. This is made to follow the star by means of a driving-clock, weighing one ton, controlled by a double conical pendulum which is placed near the top, and within the column, and is reached by a landing from the spiral staircase. At the side of the great tube three small telescopes of 6-inch, 4-inch, and 3-inch apertures are attached, which serve as finders.
The magnifying power ranges from 180 to 3,000 diameters. The object-glass is 36 inches clear aperture, and weighs, with its cell, 532 pounds. By special accessories, the telescope is adapted to spectroscopic, photographic, and micrometric work. The center of motion is 37 feet above the base and when the telescope is pointed to the zenith the object-glass is 65 feet above the base of the column. When turning the instrument in declination the weight that is put in motion is seven tons, and when turning it in right ascension 14 tons is being moved. The total weight of the instrument is 40 tons.
