1, first make sure the operation is normal. Sometimes some users don't learn to use it at first, and if they accidentally touch some knobs during use, it will also lead to this phenomenon, so first of all, I suggest you operate it again according to the correct operation steps:/zhishi04shuangtongwangyueanjingcaooo.html.

2. If you used it well before, this problem will begin to appear now. What's important is that if you can't do it according to the above, you can basically be 95% sure that there is something wrong with the telescope. It is generally caused by some bumps in the use process. You should also pay attention to this thing in the future, and try to avoid bumping.

3. If 1 and 2 meet the requirements, then there is no way to solve it by yourself. The optical axis is damaged and needs to be returned to the production line for instrument maintenance. You can contact the original seller and ask him to fix it for you.
