Fred, you wont get Newton rings with a colour camera, what you will get is loss of definition due to the Bayer matrix in the colour camera. I believe that the older PST's have a shorter eyepiece tube and can reach focus with a camera. Using Flats can help with Newton Rings. Maybe a visit to Solar Chat Forum could be an option.
