I bought this mount several years ago on Astromart. It is an Alt Az cradle mount built by a home machinist who knew what he was doing. Many astromarters have asked about it, and it always stirs interest from other observers. The socket head set screws allow adjustment in every axis. I added a very heavy machined base (visible at bottom of photo)that affixes to the top of my Bogen/Manfrotto 3036 tripod (or any other tripod with 3/8" fitting). I've used this mount with a Tak FS-78, TV85 and Sky 90, and it should work just as well with any comparably sized refractor. Price is $150 shipped in ConUSA and I have more photos if you're interested.
