Hi all,
Working with a Borg binocular telescope (ED100) most of my eyepieces, including all of the short FL ones, require placement a half inch above their resting position to come into focus. This creates annoyances in collimating the dual eyepieces. I have been all over Anacortes, but the simple device I seek--a 1.25 inch internally threaded half inch extension tube, to extend the useful length of the EP holders--seems not to exist. Any ideas? I could always get O-rings at the local hardware store but that seems inelegant...
