ABSTRACT:
The present invention relates to a novel land based reflecting telescope having a stationary, equatorially mounted, segmented mirror comprised of a plurality of movable mirrored collectors. These movable collectors are arranged in hexagonal groups to form a multiple mirrored reflector, which comprises the stationary compound telescope. A secondary mirror mounted atop a tower at the focal point directs the image toward the observation cart. Observers ride the periphery of the stationary mirror at a rate of one revolution per day. A retractable air supported hypalon cover protects the large primary mirror structure.
