pay in 3 equal parts
Dörr 533450 binocular Porro Black offers 11x magnification combined with large 70 mm objective lenses, designed for long-distance observation and astronomical viewing. The instrument uses BAK-4 Porro prisms and fully multi-coated front lenses to deliver a contrast-rich, colour-true image across the field. The binoculars feature a large centre focus wheel, dioptre correction and fold-down eyecups to accommodate eyeglass wearers. Rubber armouring improves grip and provides basic protection against dew, fog and light rain. A 1/4" tripod mount is located beneath a screw cap under the centre wheel for optional tripod attachment to reduce image blur at high magnification.
The 11x magnification allows detailed views of distant terrestrial subjects and celestial objects. The 70 mm objective diameter increases light transmission for brighter images in low-light conditions. BAK-4 Porro prisms and fully multi-coated optics deliver improved contrast and edge-to-edge sharpness. The large centre focus wheel enables quick and precise focusing of both eyepieces simultaneously, while dioptre correction and fold-down eyecups provide individualized comfort for users with and without eyeglasses. Rubber armouring enhances handling and offers protection against light moisture.
Open the eyecups or fold them down as needed for use with or without eyeglasses. Set the binoculars to the approximate interpupillary distance, then use the large centre focus wheel to bring a distant object into sharp focus with both eyes. Adjust the dioptre correction on the designated eyepiece to compensate for any difference between your eyes. For astronomical or very distant targets, mount the binoculars on a tripod using the 1/4" tripod mount beneath the screw cap under the centre wheel and, if needed, a binocular tripod adapter for secure attachment. Store eyepiece and objective caps on when not in use and keep the included carrying bag and strap for transport.
Because of the high 11x magnification, use a tripod or a stable support for prolonged observation or for night sky viewing to minimise image shake. Clean lenses with the supplied cleaning cloth and avoid harsh chemicals; keep the rubber armouring dry and store the binoculars in the provided bag when not in use.
