Apochromatic refracting lens: multilayer antireflection coating/optical aperture, achromatic lens imaging is clear and sharp, brilliant colors, low chromatic aberration, bright observation scene, large optical aperture, less brightness loss, high brightness, and clearer.
Two-speed focusing wheel: more detailed photographic observation: you can adjust different speeds to track star targets according to your own observation needs, which is convenient and quick.
Astronomical telescope focusing tube: the scale has the function of assisting focusing; the scale can be directly called when used for the second time, and then fine-tuned to focus. There is a fixing screw on the top of the long tube to prevent the focus from sliding after adjustment.
