The Bresser Spezial Astro 25x70 are astronomical binoculars with a magnification of twenty-five times, which will also be perfect for observing distant landscapes.

In order to ensure the highest possible light gathering, which is crucial when admiring the night sky, the binoculars are equipped with 70 mm front lenses. Porro prisms made of BaK-4 optical glass and a full multi-layer coating covering the entire optical system are responsible for ensuring high image quality.

Due to the large offset of the exit pupil, this product can also be used by people who wear corrective glasses without any problems. Due to the size and large magnification, the manufacturer made it possible to mount the binoculars on a tripod, after equipping it with a dedicated adapter.
