Зрителна тръба Bresser Spektar 9-27x50, 9-27x оптично увеличение, диаметър на лещата 50mm

Bresser Spektar 9–27x50 compact spotting scope with 9–27x magnification range and 50mm objective lens diameter ensures bright views even in poor light conditions (at 9x magnification). Small magnification is convenient for panoramic viewing, while high magnification provides detailed images of specific objects of your interest. The shockproof body has a standard tripod socket. During long-term observations, installation on a tripod is strongly recommended – that way you will avoid hand fatigue and, its consequence, images shaking. The spotting scope has Porro prism optical design; the prism is made of high-quality BK-7 multi-coated optical glass. The close focus of the instrument is 5 meters away from the observer. The spotting scope is very compact and portable. The package includes a special case for storage and transportation.
