Peter, First contact Prior as Andy suggested. I'll bet that if you take the
eyepiece in both hands, one hand on the top plastic part and your other hand
on the metal part and gently twist (gently mean gentle twisting) it will
come apart safely. There will be a place to insert a reticle either on the
eyepiece diaphragm or above it. There maybe a screw off ring to hold it in
place. Please ask Prior what size the reticle should be before you order.

Be carefull but have fun!
