SVBONY Diagonals

SVBONY diagonals turn the light path 90° or 45° for a comfortable viewing position. Dielectric mirror diagonals, the SV188P and SV223 ClickLock in 1.25" and 2", give high reflectivity, while the SV188 zenith mirror and the SV221 brass mirror are simpler options. The SV221 and SV222 prisms give a correct, upright image at 45° or 90°, useful for spotting scopes and daytime viewing.

The ClickLock clamp holds eyepieces centered and secure.
