It features 45° Angled Viewing, 63° Wide Apparent Angle of View, Both Eyes Open Viewing, 35x magnification with 95mm Models, 30x magnification with 65mm/85mm Models, SWAROVISION and SWAROCLEAN Systems, Nitrogen-Filled, Water and Fogproof, Removable and Adjustable Forehead Rest, etc.

It works perfectly with all versions of Swarovski’s ATX and STX spotting scope systems to give optimum effectiveness. With its cutting-edge double-eyepiece binocular configuration, you can view with your two eyes thereby giving you an edge over users of the traditional single eyepiece. The eyepieces are set at a 45° angle to the optical tube while their head stays in a natural viewing position. When used with 85mm and 65mm models, you will get a magnification of 30x while 95mm models will boost it to 35x.

Our Take on the Swarovski BTX 30x/35x:

The Swarovski BTX 30x/35x Eyepiece Module boasts of the SWAROVISION system, which helps in boosting color clarity, fidelity and contrast. You won’t mind its SWAROCLEAN coatings, which guarantees perfect clarity of the lenses and makes them easy to clean. There is an adjustable forehead rest that helps in boosting stability as well as the maintenance of the head position in connection with the eyepieces. You can remove the forehead rest if you are convenient without it.

This Eyepiece module is filled with nitrogen to prevent internal fogging when the temperature moves to the extreme. It is O-ring sealed to prevent water from penetrating to the point of damaging it. Swarovski comes up with an advanced aiming aid so that you will be able to get the most satisfactory result. You only need to place the unmagnified device in front as well as to the side of the right eyepiece before zeroing to the optical tube. Then, you just need to view with aid of the sight hole and center your target in the reticle. You can remove the aiming aid if you don’t mind using the objective modules shade’s integrated sight.

Besides, this eyepiece module boasts of High-definition (HD) fluoride glass lenses so that there will be a perfect reduction of chromatic aberration. The Field-flattener lenses fix spherical aberrations, and that is why you can be confident of views free of distortion.
