This deck was custom made to support the SBIG ST-4 autoguider on the tripod thus consolidating all the wiring under the mount. There are places for a camera or diagonal with acquisition eyepiece attached whichever is not mounted on the telescope at the time. There are extra 2" and 1 1/4"holes for whatever else you need to have ready at hand.
The deck is made from 3/4 inch birch faced plywood with a polyurethane finish. It must be mounted on the tripod before the computer and equitorial head are attached to the tripod head. It may be rotated around the mount while attached to suit your situation.
Yours for $125 plus $10 shipping.
Thanks for looking!
