Exclusive of 29,408 for Charles O'Conor, Ind. Dem. THE PRINCIPAL TELESCOPES IN THE WORLD. Astronomical telescopes are of two kinds, reflecting and refracting. The former is essentially a concave mirror or speculum, at the focus of which an eyepiece is fixed. Formerly the speculum was constructed of an alloy of copper and tin, ground to the required curvature and highly polished. In late years, however, the mirror is a glass disk, ground to the proper curvature, on the concave face of which silver is deposited by chemical sists of an achromatic liens or object-glass mounted in one end of a tube, at the other end of which, at focal distance, the eyepiece is attached. Most astronomical telescopes, and all refracting instruments, are equatorially mounted; that is, the motion on one axis is in the plane of a parallel, while that on the other is in the plane of a meridian. Most telescopes are mounted so as to be geared to clockwork that exactly neutralizes the rotation of the earth. REFLECTING TELESCOPES. processes.
