SWAROVSKI PA Adapter Ring ATS / STS

The iPhone Digiscoping Adapter Ring from Swarovski connects your PA Series iPhone Adapter to the eyepiece of the ATS, STS, ATM, or STM Swarovski Spotting Scopes. This adapter ring, together with the PA adapter, allows you to use a select Swarovski Spotting Scope as a high power telephoto lens. Simply thread this ring to your PA Adapter and slide it over a scope's eyepiece. This ring is made of anodized aluminum and has a rim knurl which provides a good grip.
