Outdated Product
High magnification premium optics (25x magnification). It is intended, first of all, for studying the starry sky or observing objects that are at a considerable distance. Perfect for use in low light conditions. The large 100mm objective lenses collect enough light so that the Sigeta Asterial 25x100 binoculars can provide a sharp, clear, bright image. The case is made according to the Porro scheme using prisms made of BaK-4 glass. They have a full multilayer anti-reflective coating. Focusing optics - separate. The device has mechanisms for diopter correction (±4 D). The hermetic and moisture-proof housing is filled with gas inside. The halves of the binoculars are interconnected by a central aluminium support rod. Since the device is large and heavy (4500 g), it is possible to mount it on...a tripod. The kit includes a durable case with metal locks, reinforced corners and a soft bed for binoculars.
