SkyMaster Pro binoculars are an ideal choice for astronomy enthusiasts and those who conduct long distance field observations. Compared to other low-cost, large-aperture designs, SkyMaster Pro binoculars are carefully crafted with precision optical elements coated with anti-reflective coatings. XLT coatings known from the Schmidt-Cassegrain system telescopes and Celestron refractors were used to cover the lenses. The heart of the Sky-Master Pro 20x80 binoculars are very large lenses with a diameter of 80mm providing a range of stars appropriate for astronomical purposes. Thanks to the huge amount of collected light, the binoculars can be suitable for twilight observations in low light conditions. All air-to-glass surfaces are covered with XLT coatings. The total transmission of light also improves the use of BaK-4 glass prisms. The binoculars have a vertical tripod mount that does not require additional angle adapters. This mounting allows you to move the binoculars in the longitudinal axis, which allows you to properly balance the equipment. Interestingly, the binoculars are equipped with a mounting rail that allows you to attach a Red Dot type finder. The Sky-Master Pro 20x80 binoculars are one of the lightest binoculars in its class. The body is made of polycarbonate and aluminum is used in places of critical importance for the construction. The whole was covered with a comfortable and resistant to destruction of the rubber layer. The binoculars are completely waterproof and nitrogen-filled, which avoids internal fogging.
