Sky-Watcher 80/600 APO ED OTA PRO is a perfectly designed apochromatic optical tube. One of the elements of the lens system is made of high-class low-dispersion ED ED (FPL-53). The novelty is the use of German glass company Schott AG, leading in the field of glass for optics as the chronicle of glass (the owner of Schott is 100% Carl Zeiss AG - a company known for the highest quality visible in optics design, what materials are used). All in all, we get the optics of one of the highest in the world, for a price that is a fraction of the price we have to pay for the tubes of Japanese brands with analogous parameters.
Each glass-air surface was covered with layers of MHC (called "Metallic High-Transmission Coating"), ensuring efficiency on a single border of 99.5%.
The offered set is a "naked" tube, a clean astrograph without visual observation accessories, which the tube can always be retrofitted with.
