Excellent optical performance: 17mm large eyepieces, new visual experience. The BAK4 high-quality prism is a glass with a higher refractive index than BAK7, which can effectively improve the light transmittance. The objective lens adopts all-optical FMC broadband green film, high light transmittance, no chromatic aberration, bright image, clear and sharp, low refractive index of green film, and reduce eye fatigue.
Large caliber, ultra-clear: It is well known that large magnifications are indispensable for large apertures, 50-60 calibers are quite comparable to astronomical calibers, so they are excellent in terms of clarity; small-caliber telescopes are easy to carry. However, the image clarity is inferior to the large aperture, because the size of the aperture directly determines the amount of light entering the telescope. The more the light enters, the clearer it is! Larger field of view, light and l
Easy to adjust: exquisite focusing hand wheel, special anti-slip hand wheel design, just turn the hand wheel to debug clear picture, get high-definition imaging, and feel more comfortable. Due to the difference in visual acuity between the left and right eyes, first adjust the sharpness of the left eye and then gently turn the right eyepiece until the sharpness is achieved. Internal metal structure, external environmental protection rubber feels good, non-slip, no damage, high quality guarant
High cost performance: high magnification, continuous magnification. Pulling distance = actual distance/magnification, so the magnification determines how long Wangyuan can see. The maximum magnification of this telescope is 120 times, which is a professional multiplier of handheld telescope. The number of steps of the zoom is freely zoomable, and the effect is stronger than that of a telescope of the same level, because the zoom telescope already has the option of multi-function telescopes
Ergonomic design: new comprehensive eye mask, humanized design When you wear glasses or no glasses, you don’t need too much sorrow, just keep the proper distance, you can eliminate the black circle of vision and avoid eyelashes. Touch the lens.
