Be careful with this statement - perhaps a bit of an oversimplification, Bill. It depends on the number of reflections in the scope.
A straight through refractor (no diagonal) should be the same as a newt and a straight through cassegrain (2 reflections). A refractor with a diagonal (1 reflection) and a cassegrain with a diagonal (3 reflections) will be the same but opposite to the first lot.
However, if you start with big adjustments, you'll soon work out which way is right or wrong.
