Takahashi dual speed focuser / MEF

I have for sale one of the original MEF-2 dual speed focusers - these are really scarce and collectable now. These are 10:1 reduction, whereas the new versions (MEF-3/4) are 7:1.

Condition is excellent. Includes a custom made by me brass torsioner / anti-rotation plate (the originals are stainless steel thin plate) that fits the spacing for 2.7" Tak focusers. You'd need to buy or make a new torsioner for different focusers. Includes the small attachment screws for the plate. These can be made to fit other focusers also - either shim the inner hole or bore it out.

New price for the newer version is $310.

My price for this one is $200 posted.
