The choice and use of bird watching telescope
A single scope telescope mainly includes the eyepiece, objective lens, focusing wheel, eye mask, and front and rear lens covers. These are all important parts of the scope.
In two steps, first assemble the monocular, then connect it to the tripod…
The tripod is connected to the monocular
Join the quick release plate on the tripod with the monotube and link it to the tripod.
With the basics of binocular operation, the operation of the monocular telescope is easier to master…
Familiar with the various parts on the tripod (different tripods have different operating methods), and be able to master the use of the tripod;
When observing, the body is facing the observation target, by moving the handle, the lens of the monocular telescope is aligned with the observation target as much as possible. Observing from the eyepiece, the object is basically in or near the field of view, and then fine-tune up, down, left, and right to make the target In the middle of the field of view (this operation requires repeated practice);
Adjust the focus through the focus wheel to make the object clear. If you need to zoom in, adjust the zoom ring to magnify the object to the corresponding multiple (20-60 times) according to your own observation habits…
Double Focus Spotting Scope
Newly designed coaxial two-speed focus wheel for smooth and accurate focusing. The fast focus wheel helps you lock on to the target quickly, and the fine focus wheel magnifies the target and gets more details
Double Focus ED Lens Spotting Scope
ED glass is a special optical material that has unique dispersion properties when combined with other glasses, which can minimize the impact of secondary spectra. Compared with achromatic lenses made of standard glass, ED glass can reduce dispersion aberrations. So the color edges are pronounced.
Single Focus Spotting Scope
It is generally recommended that the diameter of a bird-watching monocular is between 50 and 90 mm. The diameter is closely related to the size, weight, and magnification of the telescope. Too small an aperture will cause the effective magnification of the telescope to be too low, making it ineffective for precise observation. A too large aperture means a larger volume and weight, which is not a problem for birdwatchers to carry a big guy while climbing mountains and wading in rivers. Something easy. At present, the diameter of mainstream bird-watching scopes is around 80 mm. For less enthusiastic birders, they like to bring a small-diameter 55 mm bird-watching scope when going out. For female bird-watching enthusiasts, the diameter between 50-65 is not enough. It will cause a physical burden, and the matching tripod and head can be made lighter.

First Manufacturing Process, then Optical.
As the distance extends, the light transmittance through the telescope attenuates, and the refractive index dispersion of different wavelengths of light exacerbates, causing image blur. This demands a precisely calculated optical system and a streamlined manufacturing process to ensure the clarity of distant targets. This is inherently a non-trivial task in the context of optical principles.
Here, the refractive index dispersion refers to the phenomenon where different wavelengths of light experience different degrees of refraction when passing through the optical medium of the telescope, leading to the inability of the light of various colors to converge precisely at the same point, thus resulting in image blur. The need for a carefully designed optical system is to correct and compensate for this dispersion effect, while the lean manufacturing process is crucial to ensure the accurate implementation and consistency of the optical design, ultimately achieving the goal of clear imaging of distant objects.
Fully Multi-Coated
Flat Field Eyepiece Group
One of our design objectives for optical systems is to ensure that the field of view remains undistorted, particularly for long-range spotting scopes. The primary design goal of a flat-field eyepiece is to eliminate field curvature. In ordinary eyepieces, the image plane is curved, which leads to a degradation in image quality at the edge of the field of view. To correct field curvature, it is necessary to employ complex combinations of optical surfaces. It is also requisite to select materials with appropriate refractive indices, Abbe numbers, and dispersion characteristics. Different application scenarios may demand different combinations of materials.
For instance, by using combinations of lenses with multiple different curvatures and precisely calculating the curvature, thickness, and refractive index of each lens, the image plane can be made as flat as possible. This involves complex optical design software and a large number of simulation computations, as any minute change in parameters may affect the correction effect of field curvature.
