Abstract
A telescope has a primary light mirror structure including a central base, and a concave primary mirror having a central opening in which the central base is received and extending radially outwardly from the central opening. The concave primary mirror has an inner margin adjacent to the central opening. A secondary light mirror structure includes a secondary mirror having a center and an outer periphery. The secondary mirror faces the concave primary mirror and the central base of the primary light mirror structure. A spider support extends between the inner margin of the concave primary mirror and the center of the secondary mirror facing the central base. The spider support does not extend to the outer periphery of the secondary mirror. The spider support has openings therethrough to permit light rays to pass between the secondary mirror and the central base of the primary light mirror structure.
