I think you're saying that I need a 20mm eyepiece, the guy who sold it
to me says I need a 23mm.

*You* said it measures 20mm.  Then 23mm won't fit.

Your eyetube barrel is just over 20mm inside diameter, correct?

It's 20mm, but if I take out the "barlow lens" tube it's 23mm.

The two eyepieces I'm using fit into the barlow lens tube piece. I'm
not sure it will focus without it because there's a lens on the bottom
of it. I take that tube out when I insert the camera that connects to
my computer.
