I picked up an ETX-125-EC at a garage sale.  It would not focus.  Thinking that the focus knob might be loose on the shaft, I removed the knob and tried just turning the shaft, to no avail.

BUT as I was moving the telescope the shaft disappeared into the housing and I heard a mirror drop inside.  I have been looking for either a parts diagram or other instructions on how to disassemble the unit so that I can, hopefully fix it.

Any help would be fully appreciated.

This is probably one of the best resources for the ETX platform.

Gday dmadfes

I dont know how many variants of the ETX-125 tube/focusser there were

but have attached what mine looked like.

The OTA simply screws off but you might need a strap wrench to get it moving.

To remove the barrel only takes 3 screws in the back of the plastic housing.

Whatever you do, dont point the OTA "nose down" if the sled is free to move.
