Maven CS.1 15–45×65 ED Spotting Scope

The Maven CS.1 15–45×65 is a versatile mid-range spotting scope for hunters, birders and wildlife observers who need additional magnification without carrying an oversized optic.

Its 15–45× zoom range allows you to scan terrain at lower power and inspect distant details at higher magnification. The 65mm objective lens provides a practical balance between light-gathering performance, size and weight.

Extra-low-dispersion glass helps control colour fringing and preserve fine image detail. Fully multi-coated optics and a phase-corrected Schmidt-Pechan prism system produce clear, high-contrast images with accurate colour reproduction.

The CS.1 is available in two body configurations:

• CS.1A Angled: Comfortable for extended viewing and easier to share between users of different heights.
• CS.1S Straight: Provides faster target acquisition and natural alignment when viewing from a vehicle or window mount.
