Optical Telescope Assembly

Assembly

Three-mirror anastigmat telescope: 18 hexagonal beryllium segments form a 6.5 m primary that reflects light to a secondary on a deployed tripod and on to the instruments at diffraction-limited quality. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
