Swarovski Eyepiece Wide Angle 25-50x for ATS/STS - ATM/STM - STR - CTS

25-50-fold wide-angle zoom eyepiece
The Swarovski Optik eyepiece is waterproof and compatible with the telescopes of the ATM/STM-- ATS/STS series and the CTS. A protective glass prevents the ingress of dust and dirt, even when the eyepiece is removed.
The bayonet connection ensures a quiet and easy change, and the automatic locking system prevents accidental unscrewing. Additionally, the eyepiece comes with eyepiece protection caps.
Thanks to the non-stick effect of the SWAROCLEAN outer surface coating, cleaning of objective and eyepiece lenses is significantly easier, especially from dried mineral residues (e.g., water spots from condensation), insect repellents, and tree resin.
The lenses require less intensive cleaning, which significantly increases the longevity of optical products.
