Abstract
Secured to the barrel of a reflecting telescope is a large mounting ring the axis of which is perpendicular to the barrel axis. The mounting ring extends from an intermediate location on one side of the barrel, around the mirror end of the telescope, and back to an intermediate location on the opposite side of the barrel. The combination of the ring and barrel has its center of gravity approximately at the location of the ring axis. The ring is supported in a cradle on frictional pads. Because the telescope is well-balanced, friction alone can be relied upon to hold the telescope in any desired elevational position. An undercut circumferential groove is provided in the periphery of the mounting ring, and rollers within the undercut groove urge the ring against the frictional pads. The force with which the ring is urged against the pads can be adjusted in order to vary the degree of friction, and also to lock the telescope at a desired elevation. Using a Cassegrain or similar optical configuration with a diagonal mirror, the eyepiece can be positioned on the ring axis and remains stationary as elevation is adjusted.
