Leica Extender 1.8x

Leica Extender 1.8x is a magnification extender designed for Leica APO-Televid and Televid HD spotting scopes (angled model), allowing nature's details to stand out more clearly and from further away. This accessory increases the magnification range of Leica zoom eyepieces by a factor of 1.8, enabling up to 108x magnification with a 20x–60x zoom eyepiece. Fine structures of subjects, such as fur and feather details, are rendered sharply even from long distances, and observation is precise without unnecessary adjustments.

The design features an automatic bayonet lock, ensuring quick and secure attachment between the spotting scope and eyepiece. With a single motion, you can switch between normal and extended magnification ranges, enhancing usability and making the system versatile. Its compact size and lightweight (92 g) facilitate portability and quick setup in the field.

The optical assembly is waterproof up to 5 meters (16.5 ft), making it suitable for demanding use in various weather conditions. With the Televid 65 body, the close focus distance is 3.5 m, and with the Televid 82 body, it is 3.8 m, supporting precise examination of nearby subjects. The field of view and exit pupil scale reliably with magnification, and the twist-and-pull eyecup along with compatibility with eyeglasses enhance viewing comfort even during extended sessions.
