DESC: The ATS/STS 80 (HD) observation telescopes set the highest standards among telescopes in this category. Even with the easy-to-handle fully rubberized armouring, the ATA/STS 80 (HD) are by far the lightest of the larger observation telescopes. Thanks to a recalculated optical system, they offer a precise observation of detail, optimum edge-to-edge images and almost 100 per cent colour fidelity with an extremely wide field of view, thereby achieving a revolutionary image quality.
