What you are missing is called simply 2" Eyepiece Adaptor. It has
a bevel at one end that inserts into the open end of the focuser, and
two knurled knobs at the other end for retaining the eyepiece. It is
approx. 45mm long. I have been involved with a lot of SW scopes, and have never known a new one to be delivered without one.
