Baader Ultrashort 2" eyepiece clamp (12 mm backfocus) to mount onto the Carl Zeiss M68 System thread. Both sides of the clamp are equipped w. M68 male threads. This allows to integrate this 2" clamp into a series of M68 extension rings to work as 2" eyepiece holder for eyepiece projection - or to accommodate the FFC 4x Fluorit-Barlow into the beam of light - or to mount a Baader 2x or 4x TelecentricSystem.
The Ultrashort clamp M68 mounts onto all Baader Steeltrack and 3.5" Hyperion focusers. It is the best solution to couple heavy equipment like H-alpha filters or CCD-cameras onto any telescope.
