SV223 Diagonal 90-degree Clicklock 99% Reflective Dielectric Coating - W9180

The SVBONY SV223 90-Degree Click-lock Diagonal is designed to enhance your visual observation experience by providing high reflectivity and secure accessory attachment. With its Click-lock locking mechanism, this diagonal ensures a firm and stable connection, preventing eyepieces from slipping or misaligning. The 99% reflective dielectric coating maximizes light transmission, delivering sharp, bright, and high-contrast images for planetary, lunar, and deep-space observations.

Available in two sizes—1.25 inches and 2 inches (with a 1.25-inch adapter)—this diagonal is crafted from high-quality aluminum with internal anti-reflection baffling for optimal contrast. The 90-degree deflection angle provides a more comfortable viewing position, reducing neck strain during extended sessions.

Key Features:

✔ Click-lock Locking Mechanism – Provides ultra-fast, secure clamping to hold eyepieces in place without slipping.

✔ 99% Reflective Dielectric Coating – Ensures high reflectivity and optimal image stability.

✔ Premium Build Quality – Made from high-quality aluminum with internal anti-reflection baffling for superior contrast.
