STX Spotting Scope Modular Zoom Eyepiece (Straight Viewing):

This eyepiece is compatible with the STX-65, STX-85, and STX-95 objective assemblies. The straight-view configuration is well-suited for digiscoping and long-duration observation with your premium Swarovski optics.

Swarovski Optik ATX/STX/BTX 85mm Objective Lens Module: Representing the mid-sized option in their line of modular spotting scopes, the Swarovski Optik ATX/STX/BTX 85mm 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 model draws in more light and produces a larger exit pupil to improve its low-light capabilities and make it an invaluable companion from dawn to dusk.
