Hi Chuck. Thanks. The eyepiece assembly easily unscrews and comes off, but the retaining ring that hilds the reticle is quite tight and will require a real spanner to unscrew, not just a jeweler's screwdriver in one of the two slots (my usual method). As far as the eyepiece itself, when I turn the knurled knob, the entire assembly unscrews. Shouldn't it turn independently of the eyepiece and cause the eyepiece to go back and forth like binoculars to allow focusing? I fear that part is frozen up. The illuminator assembly also comes off easily. The filters work great and are nice and clear like the rest of the optics.
I am going to make a triangular aluminum mounting plate out of 1/4" thick stock to attach to the three outer mounting holes in the base, and dril and tap a 1/4-20 mounting hole in the center of the plate for tripod attachment.
