Vixen giant binocular telescope BT-81S-A
The double refractor allows for completely relaxed observations which are not possible with a simple telescope or a binoviewer. Contrast and perception of fine detail will make every observation unforgettable.

With 4.1 kg, the BT-81S-A binocular telescope is surprisingly lightweight and very portable.

Daytime viewing is also exciting with these big binoculars. Even in difficult lighting conditions, like in late dusk, colours are perceived and the image stays brigth and contrasty through the large aperture.

Together with the proven magnesium fluoride coating, the large aperture of 81 mm offers a razor-sharp and contrasty image.

Customisable magnification through 1.25" receptacle.
With the standardized barrel size of 1,25", almost all astronomical eyepieces can be used, with focal distances down to approx. 10 mm (magnification 48x).

The eyepieces are simply inserted, the interpupillary distance can be comfortably adjusted, and sharpness is achieved by individual eyepiece focusing, which also includes diopter compensation.

In order to take full advantage of the quality of the Vixen objectives, we recommend moderate wide angle eyepieces with very good observing properties, like the TS NED series.
