Hi Bryan,

BS> how can I calculate the position of the focal plane?

You may be best to make a scale drawing. IME the focal point of
eyepieces can vasry from 50mm below the focusser lip to 6mm
above it so you should allow for that when placing your
focusser. The piece of software below may help you.
