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. Start with the setup that suits you now, then add a larger objective or a different eyepiece module later.

Eyepiece modules

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

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.

Upgrades

The ME 1.7 extender increases magnification by 1.7x. The TLS APO telephoto lenses (23, 30 or 43 mm) turn your scope into a super-telephoto lens for your camera.
