Step 3: Taking the binocular apart
Take the cord out, it is fastened by special screws. Underneath is another screw, unscrew it.
The small telescope (monocular) can now be carefully taken from the connecting/ focusing bridge, 2 small steel balls will come out as well.
For this project, it is sufficient to just use one of the monoculars. However, to get some understanding of the optics, why not take the other half apart .
