The monocular telescopic telescope is an optical system that keeps the incident parallel beam emitted in parallel through the objective lens and eyepiece. It is used to observe the visual optical instrument of distant objects, which can enlarge the small opening angle of distant objects according to a certain magnification, so that it has a larger opening angle in the image space, make objects that cannot be seen or distinguished by naked eyes become clear and recognizable. Therefore, monocular telescope is an indispensable tool in astronomy and ground observation.            List of product accessories
