If only it was that easy rowena. When it comes to prime focus Newts are a bigger challenge than SCTs, unless specifially designed for it or modified to do it. Its not so much the connecting as not having enough back focus. SCTs and refractors generally have a lot of focal travel (I have nearly 15 cm on my refractor). Newts focal travel is much much shorter. If I understand it correctly you just can't rack the focuser out far enough to get a clear image to form on the film/ccd surface. Hence the need to shift the mirror or change the focuser design.

Hope someone comes along soon and answers this better than I can. Newt un-genius here.
