The Swarovski BTX 30x/35x Eyepiece Module for ATX/STX Spotting Scopes is compatible with the full series of Swarovski ATX and STX spotting scopes and provides the absolute maximum level of comfort for longer observation sessions.

The innovative design replaces the conventional single eyepiece configuration with a dual-eyepiece design. This design enables the user to have both eyes open during use, and the eyepieces are set at a 45 angle to the optical tube.

Mounted on the 65mm and 85mm models, you will have a 30x magnification with the Swarovski BTX 30x/35x Eyepiece Module for ATX/STX Spotting Scopes and on the 95mm an 35x magnification. To match the performance of the objective modules, this eyepiece features the same SWAROVISION system for a clear, contrast and improved colour fidelity and SWAROCLEAN coatings make the lenses easy to clean and maintain.

The Swarovski BTX 30x/35x Eyepiece Module for ATX/STX Spotting Scopes includes an adjustable forehead rest for improved stability and maintaining the optimal viewing position. It can also be removed if the user prefers not to use the forehead rest.

Like all models in the ATX / STX family, this eyepiece is nitrogen-filled, making it resistant to internal fogging when moving through extreme temperature changes, and it is O-ring sealed to be waterproof and submersible.
