Reach new distances with the Skymaster 25x100 high-power binocular. Never before have we offered such magnification and light gathering at such a low price. This model is great for long-distance viewing, surveillance, surveying, and astronomy.

Like all binoculars sold through Focus Scientific, they are carefully inspected for quality, and checked for optical alignment (collimation). The higher the magnification, the more important good collimation is, more-so when observing the night sky.
