M68/2 " /M68 eyepiece projection mounting plate and 2 " Steckfassung

The Ultrashort eyepiece clamp with M68 male thread and M68 and M60 adaptor threads is the shortest 2" eyepiece clamp in the M68 (ZEISS) adaptor system.

The ZEISS thread on both sides allows, for example, all 2" eyepieces up to 63 mm eyepiece diameter to be used for photographic eyepiece projection, or an FFC to be fixed in the beam path, or a TZ-2 or TZ-4 telecentric system to be mounted behind a TEC or Astro Physics refractor.

The M68 extension system can be screwed tightly in place, ensuring maximum rigidity at long projection distances and with heavy photographic equipment or a Solar Spectrum solar filter.
