Abstract
A solar telescope is disclosed that facilitates safe observation of the sun with minimal setup, targeting effort or operator skill. The folded solar telescope of the invention includes a friction stabilized telescope support system that is capable of maintaining a specified telescope orientation. The telescope further includes a targeting system that comprises one or more pointing aids to simplify the process of aligning the telescope with the sun so a solar image is projected onto a viewing surface.
Claims5
A folded solar telescope suitable for safely observing the sun, the telescope comprising:
- a folded telescope assembly that comprises an objective lens, two or three light folding devices, a second lens, and a projection surface;
- an equilateral triangular folded telescope frame in which the telescope assembly is mounted;
- a curved support device wherein the curvature of the surface to support the telescope frame is an arc of a circle that inscribes the triangular telescope frame;
- a gnomon mounted on the exterior face of the telescope frame through which the objective lens is mounted such that the gnomon is substantially parallel to an axis defined by the objective lens and the first light folding device;
- and
- a pointing target assembly comprising a small secondary aperture in the face of the telescope frame through which the objective lens is mounted proximal to the objective lens and a target on the interior of the telescope frame such that an axis defined by the secondary aperture and the target is parallel to the axis defined by the objective lens and the first light folding device.
