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.
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.
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.
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.
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.
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.
