One of the most competitive 2" diagonals on the market, this WO classic jewel is a perfect match for our new SWAN eyepieces, and will provide an ideal upgrade for cheap standard diagonals in bundle with non-WO telescopes.

Silver-enhanced coating increases reflectivity almost 10% on standard aluminum coating.
