M68 2" Ultrashort Clamp
Baader Ultrashort 2" eyepiece clamp (12 mm backfocus) to mount onto a M68 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.
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.
Finally it can be fitted directly onto a 3.3 Celestron Nut (for C11/C14, Item no. #2408145) for connection directly to these large SCT's
