The Swarovski STS 65 HD Straight Spotting Scope is part of the ATS/STS range and offers all the features that you would look for in a spotting scope: a lightweight design with cutting edge optics. Fluoride-containing HD lenses minimise colour fringing (chromatic aberration) and deliver contrast-rich images with razor-sharp outlines, which is ideal for digiscoping. The easy-to-handle fully rubberised, nitrogen filled and waterproof construction makes the STS 65 an ideal scope for outdoor viewing.
