I have one of these not being used and in excellent shape, very handy for fine focus on an SCT.
$ 140 delivered in express bag, Australia only sorry.
Info from Bintel Site
Screws on to the back of popular SCT telescopes to provide ultra-fine focus adjustments minus the image shift inherent in the SCT scopes.
Beautifully crafted with 4 precise roller bearings, tension adjustment screw, and locking screw.
Brass compression rings in 2″ and 1.25″ adapter.
The drawtube has a convenient scale to show focus positions.
