What are EP barrel extenders used for?

Hi Michael: Like if one had an eyepiece (like a long fl, in my experience) for which their focusser/diagonal arrangement did not provide sufficient travel to bring its image to sharp focus, you would use the "EBE" to provide some of than needed extra travel. I noticed three such for 2" EPs appeared recently on AstroMart 12-10-02. Joseph Wong
