You will not get a reversed view in a Newtonian (Dob), only an upside down view and that depends on how you hold your head. A straight through finder will also give you an upside down view, but a 90deg finder may be reversed or correct depending on whether it uses a standard mirror or prism or a special Amici prism.
Reversed means stars are back to front compared to a map. In an upside down view stars match the map if you simply turn the map upside down. Any odd number of reflections will give a reversed view. Any even number of reflections will give an upside down view.
