Bresser Astro 20x80 Binoculars are an excellent choice for viewing objects, in detail, located at a long distance. Wide aperture lenses allow collecting more light, and, together with high-quality optics made of BaK-4 glass, produce a bright and contrasting image with excellent color reproduction even in low light. High magnification allows for performing astronomical observations. The binoculars are also equipped with dioptric adjustment, and the rubber-armored shell protects them from moisture and dust and provides a secure grip during observations.
