you keep mentioning 'unscrewing.' Are the parts you are separating unscrewing, repeated spinning in one direction? Or are they bayonet mounts, where you twist it about 50-809 degrees and pull apart? I think this is important to clarify. Unscrewing the black-edged unit can lead to the prism possibly losing its proper orientation.
