I attached the spacing pier to the main concrete pier with 3/4" all thread. The spacer pier is constructed with 8" steel pipe and 3/4" steel plate.  The plate the scope sits on is also 3/4" plate resting on 3 bolts 3/4" diameter. The 10" LX200 EMC with the focuser and DSI-C . 
Some of Liana's extra-terrestrial scenes decorate the walls of the warm room.   The Master Control Center.  The next phase, the wedge and on to polar alignment for better imaging. A much needed April snow, about 16" total.
