Swarovski Optik ATX/STX/BTX 115mm Objective Lens Module 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 extra-large objective, versus the 65mm, 85mm, and 95mm 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 115mm objective strikes a nice balance between light-gathering ability and portability, making it well suited for the hunter, outdoor enthusiast, or birder.
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.
