Designed for bird watching, nature research and long-distance landscape observation. Premium optical performance, ultra-portable build and professional-grade imaging for all outdoor viewing scenarios.
Product Overview
EV-B55-01 single-tube observation telescope adopts an advanced APO apochromatic optical system equipped with 4 ED lens elements. It delivers outstanding sharpness and true-to-life color reproduction from the center to the edge of the frame, effectively eliminating chromatic aberration and purple fringing to restore intricate bird feather textures and natural landscape colors. Featuring 14-35x continuous zoom magnification and an ultra-wide eyepiece field of view of 57°-71°, paired with an 18mm long eye relief, it provides a full unobstructed view even for spectacle wearers.
Weighing only 1060g with a compact streamlined body, this portable telescope is effortless to carry during hiking, mountaineering and field expeditions. It serves as an all-in-one viewing device for birding enthusiasts, field researchers, industrial inspectors and entry-level astronomy lovers.
Core Optical Advantages
APO Apochromatic Design, Zero Color Fringing & True Color Rendering
2 ED elements in the objective lens plus 2 ED elements in the eyepiece form a genuine APO apochromatic optical structure. It fully corrects full-spectrum chromatic aberration and suppresses purple fringing and color edge distortion at high magnification. Every fine detail of bird plumage, plant textures and distant scenery is presented with pure, authentic and natural colors.
18-Piece Precision Optical Assembly
8 groups 11 elements for the eyepiece and 5 groups 7 elements for the objective lens. The sophisticated multi-layer optical structure corrects various optical aberrations thoroughly, ensuring ultra-clear imaging across the entire field of view without blurred edges or distorted details.
57°-71° Ultra-Wide Field of View | Higher Target Search Efficiency
Breaking the 40-50° narrow viewing limit of conventional outdoor viewing telescopes. The ultra-wide coverage allows fast scanning of woods, wetlands and lake surfaces without frequent position adjustments, easily tracking flying wildlife and bringing an immersive outdoor viewing experience.
1m Minimum Close Focus, Dual-Purpose for Near & Far Viewing
Far superior to ordinary devices with 3-5m minimum focus distance. It supports clear close viewing starting from 1 meter, perfectly adapting to long-distance observation of birds and mountains as well as close-up appreciation of insects, flowers and tiny natural details, covering both distant landscape and micro nature observation.
Large Flat Image Area, Eye-Friendly for Long-Time Viewing
Consistent high sharpness and resolution are maintained from the center to the edge of the image, achieving full-frame crisp viewing. Greatly reduce eye fatigue during long-duration outdoor observation and nature watching.
Ergonomic Upgrades
45° Angled Comfort Eyepiece: The 45° ATX inclined design avoids uncomfortable bending and squatting. You can observe freely in standing or sitting postures, effectively relieving neck fatigue during long hours of birding and outdoor viewing. The 18mm long eye relief ensures users with glasses can enjoy the complete full field of view without vignetting.
Compact & Lightweight Body: Net weight only 1060g, with compact dimensions of 255×150×68mm and a premium dark green exterior. Ultra-light and portable for hiking, climbing, field investigation and outdoor travel, easy to store and carry around.
Standard 1/4" Tripod Mount Thread: Built-in universal 1/4-inch tripod interface at the bottom of the body. It can be matched with a tripod for stable high-magnification viewing, completely avoiding hand-held shaking and delivering ultra-stable, crisp and high-definition imaging results.
Smartphone Photography Compatibility: Compatible with a dedicated phone adapter (sold separately). No professional DSLR equipment is required. You can easily capture high-resolution telephoto photos and videos of flying birds, distant landscapes and outdoor details, allowing beginners to create professional-level nature photography works.
Professional Protection Features
Multi-Layer Optical Anti-Reflection Coatings: The internal prism adopts dielectric coating and phase correction coating, while the lens surface is equipped with high-transmittance waterproof and anti-reflection film. It greatly improves light transmittance, enhances image brightness and clarity, and endows the lens with excellent water and stain resistance, adapting to dew and light rainy outdoor environments.
Nitrogen Purged Weatherproof Construction: The fully sealed body is filled with dry nitrogen, achieving three core protections: waterproof, fog-proof and dust-proof. It can cope with severe temperature changes, rainy, humid and dusty outdoor environments. No internal fogging, water ingress or dust accumulation, maintaining stable and clear imaging in all weather conditions.
Application Scenarios
Wildlife & Nature Observation: Bird watching in forests, wetlands and coastal areas, outdoor field surveys and natural science popularization, capturing subtle ecological details of wild creatures.
Landscape & Entry-Level Astronomy Viewing: Daily landscape viewing for balconies and outdoor travel, observation of lunar craters and basic celestial bodies for amateur astronomy enthusiasts.
Industrial & Engineering Inspection: Long-distance safety inspection of power lines, communication towers, high-altitude buildings and construction engineering facilities.
Sports & Live Event Viewing: Clear long-distance viewing of sports matches, concerts and outdoor live performances, capturing every wonderful detail from a distance.
Outdoor Search & Reconnaissance: Long-distance site observation, outdoor patrol and field condition investigation for outdoor exploration and public safety work.
