T2 extension rings have different use:
- 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)
- 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)
T2 extension installed (together with the M48 female to T2 male adapter) between camera and corrector in order to correctly set backfocus.
