Features:

1. The SA401 APO spotting scope is designed for birders. Professional-grade APO optical system delivers exceptional resolution, cuts chromatic aberration and provides outstanding color fidelity, edge-to-edge sharpness and light transmission.
2. It features a streamlined exterior for a sleeker profile and a built-in helical focus wheel for fast and fine adjustments. The Fully Multiple coatings increase light transmission and protect the lens from oil, scratches and dirt. The rubber armor enhances the user's durability and grip.
3. Adjustable eyecups can be twisted up and down for comfortable viewing with or without eyeglasses. The built-in sunshade reduces glare and shields the objective lens from raindrops and snow.
4. The scope can be added to a tripod or car window mount that with 1/4-20 threads on the tripod heads.O-ring seal and Nitrogen filled provide waterproof and anti-fog performance. Rubber armor enhances both durability and grip for the user.

Due to the apochromatic lens, chromatic aberrations (axial chromatic aberations) are corrected with elements of special glass with anomalous partial dispersion. The chromatic aberrations are therefore significantly below the defined limits. Bright-dark transitions in the image, and especially highlights, are reproduced almost completely free of color artifacts. The professional APO optics deliver exceptional resolution, reduce chromatic aberration and ensure outstanding color fidelity, edge-to-edge sharpness.

The large 85mm diameter objective lens (4pieces/3group) gathers more light for a brighter viewing and offers a nice observation experience especially in low-light conditions like dusk or dawn, and also works great for observing the night sky. The 24mm eyepiece (8pieces/5group) causes less eyestrain when observing.

Field of View: 114-60ft/1000yds means when viewing objects at 1000 yards, you could see an area 114-60ft feet wide. And the spotting scope brings you both wide field of view and spectacular details with the 20-60x zoom magnification.

Inject nitrogen into the scope's sealed barrel to ensures that the scope is waterproof and anti-fog, effectively preventing moisture from entering. And the scope can be used even in very harsh environments, living a longer service life.

Fully Multi-coated lens means that all lens surfaces and all air-to-glass surfaces are anti-reflective multi-layer coated. And the FMC lens increases the light transmission, delivers bright, clear and crisp images and protects itself from oil, scratches and dirt.

With K9 Porro prism, the scope has a higher quality image and less light loss, giving you a much clearer 3D image than others and also setting along with a much larger field of vision.

The big built-in helical focus wheel is smooth and accurate for coarse and fine adjustments.
