These adapters allows use of 1¼” 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.
Note: We 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.
