Zeiss Extension Tubes

Posted By Robert Williams

I recently purchased an older Telementor with the helical focuser. The scope is in good condition but is missing the extension tube which attached to the front of the focuser. I believe, but am not sure, that this extension tube is 80 mm. with the M44 thread. Without the extension tube, a simple eyepiece will not come to focus. I would like to be able to use the scope just with the plastic M44/.956 adapter and an eyepiece.

Does anyone know exactly how long this extension tube should be and where I might find one?

If I cannot find a Zeiss tube, what are some other options that would work with the M44 thread?

Thanks for the advice.
