This is a massive steel pier that can be moved around as you would with wheeley bars. It measures 51" high.
Pier is 6" diameter, 1/4 wall
Top plate is 10"x3/4" drilled and tapped with a central hole, and three surrounding holes.
Base plate is a triangle with 33" sides by 1/2"
At each corner of the base plate is a heavy duty, 3/4" screw jack to raise the pier off the ground.
The entire unit is very heavy and suitable for a large instrument. The perfect solution of vibration free observing or CCD imaging. The unit could also be installed in a permanent observatory on a concrete foundation.
This unit is too big and heavy to ship. It needs local pickup, or I could meet you halfway some reasonable distance to the SF Bay Area.
I am asking $250 for this. Thanks for looking...Ken
