Bresser Astro 20×80 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.
