ATX/STX/BTX Modules and Upgrades


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.
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.

Phils Review : "Of all the spotting scopes used for birdwatching or hunting, this scope is the penultimate scope. Whether I have been looking at wild western budgies around a desert waterhole in the late afternoon or sitting in a bush hide waiting for a flighty deer in low morning light, I have found this scope setup to be perfect for the job."
