1. Keep a proper exit pupil distance with the eyepiece. If the stickers are too close or too far away, you will feel dark shadows in the field of view when observing, and you will not be able to get a complete circle of vision.
2. Adjust the interpupillary distance. Adjust the distance between the two lens barrels to match the pupil distance of your eyes, so that the images can be seen to overlap.
3. Focusing. Slowly turn the focus wheel to focus and adjust the sharpness!
4. Do not use the telescope to observe the sun directly, as this will cause serious damage to the eyes or even blindness.
