How to use a monocular telescope:

1. Use with double adjustment. Hold the telescope barrel with your left hand, see a circular field of view, and turn the movable part of the objective lens with your right hand until you see a clear scene. The rotating part of the eyepiece can compensate for more precise focusing.

2. Use monotonically. Hold the telescope barrel with your left hand, see a circular field of view, and turn the eyepiece handwheel with your right hand until you see a clear scene. Pay attention to the scale position under the eyepiece handwheel. Generally, you can turn it to the same position when you use it again in the future.

3. Look at the telescope with your main eye and open the other eye at the same time. This can correct the direction of the telescope in time and reduce eye muscle fatigue.

4. Never use a telescope with one hand. When using a monocular telescope, you may as well use the gun-holding method, with both hands one in front and one behind, holding the barrel from the bottom.

5. Avoid using a telescope while walking. Because when using a telescope, the user cannot see the ground. If you walk during use, the user may fall or even slip.

A monocular telescope is an instrument that collects electromagnetic waves to observe distant objects. A monocular telescope is a visual optical instrument used to observe distant objects. It can magnify the small angle of distant objects by a certain factor, so that they have a larger angle in the image space, making objects that are originally impossible to see or distinguish with the naked eye become clear and distinguishable. A monocular telescope is an indispensable tool for astronomical and ground observations. It is an optical system that uses an objective lens and an eyepiece to keep the incident parallel light beams still emitted in parallel.
