The Sigeta Asterial 20x80 binoculars (with carrying case) represent the ideal optical instrument for astronomical observation and long-range object viewing.
It is equipped with high-quality optics featuring BaK-4 prisms fully multi-coated across all optical surfaces. Due to this and the large-diameter 80 mm objective lenses, a luminous and contrast image is formed, which is essential when viewing the night sky.
The waterproof and fully sealed aluminum-alloy binocular housing features Porro's classic design. It is coated on top with an anti-vibration rubber armouring protecting the binoculars from external influences. Moreover, the inside is nitrogen-purged for the prevention of the condensate formation. There is an integrated metal mounting bracket between the tubes, enabling quick attachment of binoculars to the tripod and correct weight balance.
A separated focus system is supplied for sharpness setting, ensuring precise focus adjustment even if there is a different eyesight. The eyepieces have high rubber eyecups, reducing side lighting.
The manufacturer provides protective covers for the optics: the lens covers are attached to the inside of the barrel, and the coupled eyepiece covers include lugs for attaching to the strap.
The binoculars comes with everything you need to maintain ultimate protection, either in field conditions or on the road: except for the protective covers, strap and optic cleaning wipe, the set comprises a hard carrying case padded inside that is lockable with a key.
