Scondary offset test?

Scondary offset test?

Is there an objective way to test the positioning of the secondary offset with respect to the focuser.

I understand why the center of the secondary should be further then the center of the tube from the focuser, but if you could 'diddle' the distance, could you observe the effect?

I use a LaserMax laser to check offset, but it does not give me a inch figure. You should be able to measure the distance from the focuser edge of the tube to the center of the secondary stalk and then from there to the other side of the tube ans see the offset distance that way.
