How to use and maintain binoculars
Many people own binoculars, and even many friends have military binoculars. Although they have such good things, many people do not Know how to use, how to maintain, and answer your questions one by one today.
How to use the telescope
:
1. Adjust the exit pupil distance
First of all, my The binoculars are all rotating eyecup systems. When using the eyecup, turn the eyecup to the highest first (this is usually the case). If you wear glasses or turn the eyecup to the highest, you still cannot see the full field of view or the field of view has dark shadows (shadows). , you need to adjust the eyecup to the most comfortable height for your glasses.
Second, adjust the program distance
Change the distance between the two lens barrels of the telescope until the left and right fields of view are a circular field of view. At this time, the distance between the exit pupils of the two lens barrels is the same as the distance between the two pupils of the human eye.
3. Focusing
First turn the handwheel of the center adjustment mechanism of the telescope until the left eye can see the target clearly. Then turn the diopter handwheel of the right eyepiece so that the right eye can also see the target clearly.
4. Observation
Aim the telescope roughly at the observation target, turn the center adjustment mechanism, and both eyes can quickly see the target at the same time. For scenes of different distances, you can see clearly as long as you turn the center adjustment mechanism.
Note:
Put down the eyecup after use, otherwise the eyecup may be damaged due to negligence.
Because of the focusing function of the telescope, it is not suitable to observe objects with strong light, especially the sun, which will damage your eyes.
Maintenance of the telescope:
1. Do not use other ordinary cloth to wipe the objective lens or eyepiece, use the flannel or other soft cloth included in the telescope bag Wipe the eyepiece objective of the telescope.
2. When removing the remaining dirty spots or stains, you can drop one or two drops of alcohol, preferably with a cloth, because it is difficult to control the amount of drops.
3. Although everyone buys waterproof mirrors, there will be no problems in use even if they fall into the water. But as far as maintaining the telescope is concerned, keeping the telescope in a dry environment is beneficial and harmless to the baby’s coating and telescope. The waterproof and nitrogen-filled functions are only in case of falling water and dampness, and are not afraid of dampness and mold growth on the internal optical parts.
4. Don’t try to clean the inside of the telescope or disassemble the telescope. The telescope is actually very complicated. If the optical axis is broken, it can only be debugged on the special instrument for debugging the optical axis of the telescope. As long as the telescope is disassembled, its optical axis will change, so that the imaging of the left and right tubes will not overlap, which will make your glasses uncomfortable, and can not be used at all in severe cases. Do not drop, press or other violent actions on the telescope, mainly because of the optical axis of the telescope. Heavy falls, heavy pressure or other violent actions can easily damage the optical axis of the telescope. If any glasses are uncomfortable during use, Please send it to me and I will fix it for you free of charge.
5. Do not use a telescope to observe the sun directly. This is a major precaution for all telescopes. The strong sunlight is focused by the telescope, just like a magnifying glass, which will burn your eyes.
6. Considering the cost, weight and portability, most of the current telescopes are not metal mirror bodies, which are easily damaged by heavy falls and heavy pressure. So everyone should love her like a dog.
7. The desiccant I use doesn’t really make much sense for waterproof binoculars. It’s good to throw it away after one year of failure. But for babies that are not waterproof, it is best to replace them regularly (six months to one year) to prevent the interior from getting damp and mildew. The desiccant should be available, and some products are also available, which can be borrowed.
8. After using the baby, when placing it, first check if there are foreign objects on the table, and do not put it on other items to prevent scratches or stains on the objective lens and eyepiece.
9. The telescope should still be placed in the right direction, and the eyepiece should not be placed down. (Everyone on earth knows that!) Because some parts are coated with lubricating grease, and some places are also designed with oil storage grooves, it may flow to the place where it shouldn’t drip for a long time or the weather is too hot.
