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 a high class low-dispersion 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 ("Metallic High-Transmission Coating"), ensuring efficiency on a single border of 99.5%.
The excellent mechanics are in the first place Crayford's extract with a 1:10 microfocus cage. Included with the tube is a very good two-inch dielectric 90 ° angle cap with a efficiency of 98%, a 2 "focal-length 28 mm eyepiece, a 9x50 finder with a cross and a bracket and dovetail splint.
A great tool for planetary observation and astrophoto for "piggy-back" as well as an observation telescope with outstanding optical quality.
