Allows For use of 1/ 1/4" eyepieces in any 2" focuser or diagonal.
All models feature brass clamp ring or nylon-tipped set screw for secure, no-mar locking and safety undercut.
Manufacturer purposely do not put 2" filter threads in 2" to 1¼" adapters. The reason is to avoid your getting upset when you insert a 1¼" Barlow and it crunches your expensive 2" filter. Safety first.
