T-Ring Micro Four Thirds (4/3) adapter with 19mm detachable extender

The T-2 adapter for compact cameras with Micro Four Thirds flange focal distance permits the connection of T-2 lenses with a 55mm back focus. The built-in 19mm extender included can be removed to allow the adapter to be more useful for astronomy, so that compact cameras with short adapters only have a 36mm flange focal distance from the T-2 thread.
