The TS90 was the first of a new breed of refracting telescopes* that were within grasp of the more demanding amateur. The Apos could be made with physical lengths about half as long and lighter in weight than the Unitron. Competing systems then marketed to the consumer tended to incorporate less finely made gears sets, fewer precision bearings (if any at all and their tripods tended to lack the rigidity of the products. Finder Telescope: this instrument was originally furnished with one 8x 30mm aperture finder telescope. For the more demanding clients there were optional Orthoscopic (design devised by Ernst Abbe of Carl Zeiss in 1880) eyepieces available too.
