I bought this in my almost endless efforts to address some optical issues I was having. Turns out I don't need it. It's basically brand new having spent almost its entire life in my possession within my bag of astro adapters.
This is an excellent bit of kit, so much so that I'm tempted to keep it even though I have no use for it.
Very well designed, this enables you to adjust tilt without unscrewing things from the tilt adjuster. *WAY* easier to use than cheap tilt adjusters like the ZWO (which I also have).
This is the 68mm version thus can be threaded directly into a Moonlite focuser's drawtube.
Cost to land is about $475, will sell for $350 shipped within Australia, $365 if you want to pay via Paypal.
