MGEN parfokal adaptor for Takahashi 7x50 and Skywatcher 9x50 finderscope
The Parfocal Adapter allows to connect a MGEN Autoguider to a Takahashi 7x50 or Skywatcher 9x50 viewfinder with minimal refocusing. The refocusing is done at the front of the lens, with the counter ring the object kitv can then be fixed again.
Of course, other T2 accessories can also be connected, but primarily it serves to use the viewfinder as a guide scope. It replaces the whole back plate of the viewfinder and ends with a T2 thread. Good for short viewfinders (e.g. with Amiciprisma), which should be made fit for guiding with a T2 extension. The free opening of 36mm also allows the use of seeing-calming filters in front of the MGEN camera (e.g. red filter, IR pass...).
