Baader M60a x 0.75 click lock clamp

for Vixen M60x0.75.
Baader 2″ KlickLock clamp for telescopes with M60 internal thread (Vixen
M60 thread) # 2956260.
Actuate the rotary lever of the KlickLock without any effort
mechanism and clamp a 2″ star diagonal, an eyepiece or
a 2″ adapter exactly on the optical axis. The KlickLock clamp
distributes the pressure evenly on the housing wall and stresses
so that the adapter or eyepiece is not as strong.
