Fully compatible with all versions of their ATX and STX spotting scope systems, Swarovski Optik's BTX 30x/35x Eyepiece Module represents the pinnacle of comfort for long-duration glassing sessions. The innovative design replaces the conventional single eyepiece with a dual-eyepiece binocular configuration that enables users to view with both eyes open, and with the eyepieces set at a 45° angle to the optical tube, their head is put in a natural viewing position. When mounted on the 65mm and 85mm models it has a 30x magnification, whereas the 95mm version is stepped up to 35x. Both models have a 63° wide apparent angle of view. To match the performance of the objective modules, this eyepiece module has the SWAROVISION system to improve color fidelity, contrast, and clarity; and SWAROCLEAN coatings help keep the lenses clear and easy to clean.

To improve stability and maintain the optimal head position relative to the eyepieces is an adjustable forehead rest. The rest can be removed if users find it more comfortable to use without it. Like the rest of the modules in the ATX/STX family, the Eyepiece module is nitrogen-filled to make it resistant to internal fogging when moving through extreme temperature changes, and is also O-ring sealed to be waterproof and submersible. Because finding targets through angled eyepieces is sometimes challenging, Swarovski provides an innovative aiming aid. The unmagnified device is placed in front of and to the side of the right eyepiece and is zeroed to the optical tube, so users simply look through the sight hole and center their subject in the reticle. Like the forehead rest, the aiming aid can be removed if users prefer to use the integrated sight on the objective modules shade.

Optical Performance

• Dual identical eyepieces
• 65/85mm Objective: 30x magnification with 65mm/85mm objective models; 35x magnification with 95mm model
• Proprietary SWAROVISION system improves image contrast, color, and clarity
• Wide Apparent Angle of View: 63° 
• Field of View at 1000 Yards: 114' (65mm) / 111' (85mm) / 96' (95mm)

• Long, 21mm eye relief on all models

SWAROVISION System

• High-definition (HD) fluoride glass lenses eliminate chromatic aberrations for accurate color fidelity, and improved resolution and contrast
• Field-flattener lenses correct spherical aberrations for distortion-free views, especially at the edges
• SWAROTOP anti-reflective multi-coating that enhances light transmission
• SWARODUR coatings provide enhanced scratch resistance
• Non-stick SWAROCLEAN coatings on exposed lens surfaces ensure that water, dirt, sap, and oil can be easily removed without scratching or leaving residue

Representing the second largest objective option in their line of modular spotting scopes, the Swarovski Optik ATX/STX/BTX 95mm Objective Lens Module gets an updated tripod shoe that fits Arca-Swiss quick release plates, and will accept any of the three available eyepiece modules: straight (STX) or angled-viewing (ATX), or the binocular viewer (BTX). The bayonet mount for the eyepiece modules is backward compatible with the original ATX/STX modules, to make it easy for users to upgrade their objectives without needing a new eyepiece module. This larger objective versus the 65mm and 85mm models draws in more light and produces a larger exit pupil to improve its low-light capabilities and make it an invaluable companion from the pre-dawn hours to all the way past dusk.

Optically, Swarovski combines the legendary image quality and world-class workmanship that nature enthusiasts, tactical professionals, and researchers have come to expect from the brand. The 95mm objective strikes a nice balance between light-gathering ability and portability, making it well suited for the hunter, outdoor enthusiast, or birder. Extra-low dispersion fluoride glass elements efficiently transmit all wavelengths of visible light, resulting in bright images that are color faithful, crisp, and rich with detail. An integrated field-flattener lens system corrects spherical aberrations to reveal crisp details at the edges of the view without distortion. SWARODUR and SWAROTOP coatings on all lenses and prisms minimize glare while maximizing contrast.

Complementing the optical performance and technologies is a lightweight and durable magnesium-alloy chassis that is wrapped in a protective rubber armor. Its optical tubes are nitrogen filled and O-ring sealed to be dustproof, waterproof and submersible, and resistant to internal fogging when moving through extreme temperature changes or environmental conditions. The tripod collar has a 1/4"-20 socket on the bottom of the Arca-Swiss-compatible shoe and a rotating collar to allow for precise eyepiece placement relative to the mounting system.
