A little footwork ...

I removed the fixed mounting foot from my AT 72 and drilled/tapped a new 1/4-20 attachment hole just ahead of the existing aft attachment hole. The provided forward attachment hole is almost 1-1/2 inch in front of the aft attachment hole. Using a screw in both holes to attach the quick-plate positioned the quick-plate very far forward -- on a scope that balances very far aft! The 1/4-20 attachment hole that I added to the foot allows using two screws to hold the quick-plate in a much more favorable position more to the rear of the scope.

This simple modification is not difficult -- and might be useful for any scope with a fixed mounting foot and a balance point that is actually located inside the focuser -- very far to the rear of the optical tube.
