The "tripod" is the Astro-Physics Eagle 6" Pier. It is available from AP which is where I purchased mine. I believe they still have some in stock from the most recent production run.

The Mount is the AP Mach1 GTO. I made a deal with a guy on Astromart to trade my 1200 GTO for it and the difference in price between the two mounts.
