T-2i Standard Quick Changer with Zeiss Dovetail receptor

Unfortunately, this will not work. The Carl Zeiss Jena Astro-ring-dovetail has got a different dimension than any of the micro-dovetails of either Zeiss- East or Zeiss-West microscopes.

The quick changer needs it counterpart, the changer ring #7 to be functional. The changer has T-2 inner thread, the ring T-2 outer thread. If you mount it in between any T-2 connection between two T-2 items, you can take these apart in a second without screwing. It also fits to T-2 barlow. When you put it in between for example a camera T-Ring and the barlow, you can much easier take the camera away or rotate the camera.
