Product introduction

Main features
1. Bright and natural viewing experience
The objective lens uses ED glass to correct chromatic aberration, which causes color fringing. The auxiliary prism employs high-reflectivity dielectric multilayer coatings, and phase correction coatings are applied to the Dach prism, improving transmittance across the visible spectrum, resulting in bright, natural colors and a clear view. Additionally, all lenses and prisms are coated with multilayer films to ensure a bright view.

2. Large aperture and high magnification
With an objective aperture of 56mm, it provides sufficient brightness even in low-light conditions. "20-56" is a high-magnification model in the "MONARCH" series. Even distant subjects can be captured with a dynamic field of view.

3. Excellent waterproof performance
The body is filled with nitrogen gas, making it resistant to internal fogging and mold, ensuring durability. It is safe against sudden rain or splashes, making it suitable for nature observation, astronomical observation, birdwatching, and more.

4. Pursuit of ease of use
The eyepiece uses a click-type turn slide (rotating extension) mechanism, allowing the eyepiece to fit comfortably at a position that is easy to look through. The long eye relief allows a wide field of view even when wearing glasses. It also features a flip-down objective lens cap to prevent loss.
The distance from the eye position where the entire field of view is visible without vignetting when looking through the binoculars.
