Svbony SV41 PRO Fieldscope, 28-84x 80mm MAK Cassegrain Spotting Scope, High Magnification, 800mm Long Focal Length, Compact and Lightweight, FMC

[MAK Design - 800mm Long Focal Length] The refractive optical system combines the advantages of refraction and reflection, creating an optical loop within the telescope barrel, achieving a long focal length of 800mm with a short telescope body, improving resolution and effective magnification. The short telescope barrel allows for compact construction of large-aperture telescopes, improving outdoor mobility. The much longer focal length than it appears makes it suitable for high-magnification observations. [28-84x Zoom Magnification] The 28x, 56x, and 84x zoom magnifications provide a wide field of view at low magnifications and magnified details at high magnifications. [80mm Objective Lens] Increases the amount of light entering the objective lens, strengthening light-gathering power for clearer, higher-resolution images. [FMC Full Multi-Coating] Effectively reduces light loss, providing clear, bright image details. [IPX7 Waterproof] IPX7 waterproofing prevents moisture, allowing the spotting scope to withstand harsh environments.
