The STX Spotting Scope Modular Zoom Eyepiece (straight viewing) from Swarovski is a wide-angle eyepiece specifically engineered for the STX spotting scope series. The straight configuration is well-suited for digiscoping and long-duration observation with your premium Swarovski optics. This eyepiece is compatible with the STX-65, STX-85, and STX-95 objective assemblies. Mounted with either the STX-65 or STX-85 objective assembly, this zoom eyepiece has a magnification range of 25-60x; when mounted on the STX-95 model, the magnification range is 30-70x.

This configuration of the Modular Zoom Eyepiece seamlessly integrates with the DCB II and TLS APO digiscoping adapters. These optional accessories from Swarovski allow you to transform your STX spotting scope into a formidable digital imaging platform. The accessory adapters enable integration with point-and-shoot, mirrorless, and DSLR camera systems, and they feature the build-quality and thoughtful engineering you expect from Swarovski. Now your superior optics can be used to capture high-definition stills and video of that rare bird or butterfly in your sight.

Ergonomic handling and user-friendly functionality makes the STX eyepiece an observer's delight. The eyepiece quickly attaches/detaches from the objective assembly's bayonet mount, making the scope easy to disassemble, transport, and store. Swarovski engineered the straight-view eyepiece's focus dial to precisely align with the zoom dial on the objective assembly, enabling one-handed adjustments to field of view and zoom. This feature is especially useful when tracking an object, requiring one hand to guide the tripod head. This eyepiece's generously wide viewing angle, extra-long eye relief, and click-stop twist-in eyecup makes using your STX spotting scope a world-class glassing experience.
