Keep the original screws in place for future use. 8SE, C8/C8HD have one screw at the objective end, two screws at the eyepiece end 2. First, tighten the screws by hand. If the screws cannot be fully inserted or cannot be tightened after a few turns, it is possible that the screws have been selected incorrectly. Do not force the installation again. 3. For the end with two screws, do not tighten one side at a time when tightening the screws. Tighten evenly multiple times.
