M48 extension rings have different uses:

1. They can be screwed to optical accessories (such as field flatteners or focal reducers) to bring the camera sensor at the right distance from the lens (to optimize performance)
2. They can be used to separate the mechanical accessories that, when used together, can touch and then not work properly (eg an off-axis guider could touch a filter wheel and it could prevent its rotation searching for a guide star)
