TS Extension Ring for the M54x0.75 Thread
Many focusers have the M54x0.75 filter thread as an auxiliary thread. This thread allows, for example, to screw correctors to the focuser. This ring extends the distance and thus enables optimization of the focuser´s adjustment position.
However, the M54x0.75 is also a filter thread that is often used on camera lenses. The extension also makes it possible to build your own dew shields and lens hoods.
Scope of Delivery:
The extension ring extends an adapter with M54x0.75 connection by 15 mm.
