The subject of the SW eyepiece adaptor system has been covered many times on IIS. It is actually quite simple. When new the 2"EP adaptor
has a label on it saying 2" Eyepiece Adaptor.
When using 1.25" EPs, the tube that the EP slides into comes screwed into a flat plate that has a bevel round it's periphery. The two knobs[screws] at the open end of the focuser lock onto the bevel.
When using 2" EPs the two knobs [screws] are loosened off, and the flat plate together with the tube that the EP slides into is removed. The bevelled end of the 2"EP adaptor is simply inserted into the open end of the focuser, and secured with the same two knobs [screws].
Sounds complicated, but a change of EP size can be done in less than
10 secs.
