B. When removing residual stains, drip 1-2 drops of alcohol onto a soft cloth.

C、Telescopes should be stored in an environment with good ventilation and dryness.

The correct way to use a telescope:

1.Adjust the distance between the two tubes of the telescope., until the field of view is a circular one, at which point the exit pupil of both tubes aligns.DistanceThe distance between the two pupils of the human eye is consistent..

2. Focusing: First close your right eye, look through the telescope with your left eye, and turn the central focusing mechanism (the hand wheel or press plate) until the image is clear; then, close your left eye and look through the telescope with your right eye, adjusting the right eye's eye cover (by slowly rotating it left and right) until the image is clear.

3. Observation: Aim the telescope at the target, slowly turn the focus mechanism, and you can quickly see the target clearly with both eyes. For targets at different distances, you can just adjust the focus mechanism to see the target clearly.

4. How to use the zoom telescope: First, pull the zoom lever to the lower magnification. Adjust the telescope using the above method until the target is clear. Then, pull the zoom lever to select the appropriate magnification you need.
