With a large aperture for maximum light-gathering ability to allow its use in even the most challenging conditions, Swarovski Optik designed their STR-80 HD 80mm Spotting Scope as an indispensable companion in a blind or stand, or at the range. This version of the scope is outfitted with a modified duplex ranging reticle with 0.5 MRAD indicators and stadia to assist in range and target size estimation as well as ballistic drop compensation for long-distance shots. Running on one CR123 battery with an exceptionally long runtime, the reticle is illuminated in red with 15 intensities: 10 for daytime use and 5 for nighttime. The reticle, set on the first focal plane, retains its subtension accuracy at any magnification and can be completely removed from view to allow the scope to be used as a conventional spotter.
Optically the STR-80 performs up to Swarovski’s high standards and expectations with extra-low dispersion fluoride glass elements that efficiently transmit all wavelengths of visible light, resulting in bright images that are color faithful, crisp, and rich with detail. SWARODUR and SWAROTOP coatings on all lenses and prisms minimize glare while maximizing contrast. The large aperture draws in copious amounts of light, allowing it to be used in the pre-dawn and dusk/twilight hours when animals are most active. This iteration is offered here without an eyepiece for those users who wish to choose one or both of the optional 25-50x wide-angle or 20-60x zoom eyepieces. To make acquiring subjects easy and tracking targets faster, the eyepiece is set in-line with the optical tube for straight-through viewing.
The aluminum-alloy chassis is wrapped in a rubber armor that protects it from bumps and impacts, while offering a slip-resistant grip for sure handling during setup and breakdown. A rotating tripod collar is equipped with both 1/4″-20 and 3/8″-16 threads to be compatible with most photo, video, and field tripods and other support systems. Its optical tube is nitrogen filled and O-ring sealed to be to be dustproof, waterproof/submersible to 13′, and resistant to internal fogging when moving through extreme temperature changes or environmental conditions.
