Dr. Wadsworth's 12½-inch reflector in Simcoe, Ontario. This photo was published in the RASC Selected Papers and Proceedings, 1902-03. Information was given on pp.58-59:
Dr. Wadsworth’s observatory is ten-sided, the floor 15 feet across, its walls 7 feet high, wooden, with an iron track for the dome, made of stout canvas. Its equipment is as follows:—
A silver-on-glass Newtonian Reflector with 121⁄2 inch aperture, 105 inches in focus, having powers 105, 210, 315, varied by using a Barlow lens. The telescope was constructed by its owner about ten years ago, the speculum being ground and polished by him on the principles laid down by Foucault, Draper, and Wassell. Brashear’s method is used for resilvering. The instrument rests on a metal equatorial stand of massive construction. The pillar stands on a solid base of masonry. The polar axis, three inches in diameter, and the declination axis, 2 inches, are both solid steel. The graduated circles, 13 inches in diameter, are the only parts not made in Simcoe. Cameras are attached, and clock motion applied when wanted.
