KOWA TSN774 77mm straight spottingscope (OS-KWTSN-774)

The PROMINAR models “TSN-773/774” have an XD objective lens with low dispersion properties to diminish chromatic aberration. Like the TSN-880 Prominar models, the concave lens paired with the XD lens is made of glass with special dispersion properties to reduce the chromatic aberration to a further degree. The performance and compactness of these spotting scopes are second to no other scope in this class.
