The Swarovski STX Eyepiece is a straight modular zoom eyepiece designed for the Swarovski STX observation scopes. The innovative and unique optical design provides significant improvement in resolution, contrast, saturation and exceptional colour fidelity. The field flattener lenses create a flat image, even the finest structures are reproduced with razor-sharp clarity right up to the edge with no need for contrast refocusing. This ensures that every detail is instantly captured, producing a perfect image without any distortions. The Swarovski STX Eyepiece features a long eye relief and the removable twist-in eyecup is individually adjustable. 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.
