Celestron Nature DX Focus Knob Replacement

Using a plastic opening tool, nylon spudger or metal spudger, pry into seam of the skin cover at the center of the device. Lightly lift the tool which should cause the skin cover to rise.

Start peeling the skin away from the center. Apply force as there is an adhesive substance that is binding the skin to the device. Continue peeling until skin cover slides off completely.

Repeat steps 1 and 2 for the other side.

Remove the top cover of the focus knob as shown. Simply twisting and pulling the cover will slide it off.

Use a magnetic pickup tool or magnetic screwdriver head to remove the guard. The guard should come right off without much resistance.

Unscrew the focus knob. It should come off without much resistance or pressure.
