LEONARDO BM-100 Bino Mount

Please Note: The LEONARDO BM-100 Bino Mount (black and red) is temporarily unavailable.

Since ancient times, the lever principle has been utilized in order to solve problems related to lifting big loads with minimum effort and in best safety. LEONARDO-BM100-L, the 10Micron-mount for heavy duty binoculars and spotting scopes, optimizes this principle, with the clear aim to provide all Astro- and terrestrial observers with a reliable optical platform and perfect aiming- and targeting-system.

The LEONARDO-mount is able to provide exceptionally sturdy instrument support, totally free of vibrations, and to ensure prolonged observation in total comfort. The extreme variability of the Leonardo-mechanical system enables you to observe any astronomical or terrestrial object conveniently by utilizing it´s 4-axis pointing system.

Friction adjustment hand-knobes in elevation and horizontal rotation enable the user to precisely match the preload of the parallelogram for retaining a fluid-movement with varying instrument weights - and to finetune all mount-movements to effectively compensate for accidental shock or sudden intense wind-gusts. All hand-knobes are placed conveniently, nearest to the position of the observer.

The fourth axis, defined as "scan", offers very smooth left/right movement for the optical instrument itself across a viewing angle of altogether 30 degrees. This allows to conveniently monitor moving targets, birds, planes, satellites at any hight above the horizon, without the need of having to move the parallelogram itself and without changing the observers head position.

The instrument platform at the upper end of the parallelogram is well balanced, to provide ultimate smoothness for movement in elevation with any optical instrument weight up to the Zenith..

In any viewing position, the observer always can keep a good distance from the tripod legs. This helps enormously to move freely without danger of tripping in the night.

In general, maximum care has been given, to make all movements of the Leonardo-Mount to be as smooth, well-balanced and effortless as anyway possible. Regardless whether the observer will be standing upright or sit in a (wheel-)chair or be conveniently stretched out onto a sun-lounger, always he will find the handling of all mount-movements to remain extremely effective and to allow for the most convenient head- and body position.
