ATX/STX/BTX Modules and Upgrades

Swarovski ATX, STX and BTX eyepiece modules with 65, 85, 95 and 115 mm objective modules

Build your Swarovski ATX, STX or BTX spotting scope

Swarovski's ATX, STX and BTX spotting scopes are modular. You choose an eyepiece module and an objective module, and every eyepiece module fits every objective. Most people start with a complete set, then add a larger objective or a different eyepiece module later.

Complete sets

The easiest way to buy. Each set pairs an eyepiece module with an objective module, ready to use out of the box, and costs less than buying the two separately.

ATX (angled): 65 · 85 · 95 · 115 mm

STX (straight): 65 · 85 · 95 mm

BTX (binocular): 65 · 85 · 95 · 115 mm

Eyepiece modules

Already have an objective, or want to add a second viewing style? ATX (angled) is easy to share and comfortable for looking up at birds. STX (straight) is quick for finding subjects and suits hides and car window mounts. BTX lets you view with both eyes, which is far more relaxing for long sessions.

Objective modules

Every eyepiece module fits every objective. 65 mm is light and portable, 85 mm is a good all-rounder, and 95 mm and 115 mm give the brightest, most detailed views. With the ATX and STX, the 65 and 85 mm give 25-60x and the 95 and 115 mm give 30-70x. The BTX gives a fixed 30x or 35x.

Accessories

Swarovski SOC stay-on case for the ATX eyepiece module

The ME 1.7 extender increases magnification by 1.7x, and the TLS APO telephoto lenses (23, 30 or 43 mm) turn your scope into a camera lens. Stay-on cases protect each module: ATX, STX, BTX, 65, 85, 95 and 115 mm. The BR balance rail keeps larger setups steady on the tripod.
