It has long been considered that looking through a telescope/spotting scope with two eyes is better than one......but with telescopes you only get one eyepiece..until now. Swarovski have released their new BTX binocular viewer eyepiece module for their ATX and STX telescopes.
The Swarovski BTX eyepiece module combines the visual power of both eyes with a revolutionary viewing experience. Crucial subtleties can be seen with the crystal clear optics, with every detail now fully on show. A forehead rest and angled view guarantee comfortable viewing for hours on end. The benefits of binoculars and spotting scopes are combined in the BTX eyepiece module. It presents vivid, true-to-life images and offers the comfort required for long-term observation. The BTX eyepiece module is compatible with all objective lenses in the SWAROVSKI OPTIK ATX/STX range.
Taking functionality to a new level: the ATX/STX/BTX spotting scope system combines exceptionally flexible modularity with optical perfection. The objective lens can be changed to suit any viewing situation. Extreme detail recognition at crucial moments thanks to SWAROVISION technology and total ease of use ensure fascinating experiences in the great outdoors.
