Use step and precautions:
1, Use a lens cloth or cover to cover the finder lens to avoid operation!
2, Check the Bard film directly at the sun to check if there is light leakage, and it is strictly forbidden to use it.
3. After the test is completed, put the Bard film cover on the light inlet, and check the fixation.
When it is intact, measure the light at the eyepiece and operate without abnormal light!
4. During the observation process, don't allow people on the side to move the Bard membrane cover easily.
