2" to 1.25" Self Centering Lock adapter

2" to 1.25" Self Centering Lock adapter - Self Centering Visual Back 2" to 1.25" with M48 Female Thread

It is practically a 1.25" eyepiece holder /visual back that can be plugged into a 2" eyepiece holder, thus effectively converting 2" into 1.25", but with quick locking and self centering ability.

This makes for quick an easy eyepiece swapping with no fiddling with locking screws. 
Also particularly suited for imaging due to the self-centering design. 
The teflon surface ensures the eyepieces/ accessories will not be marked.
