These adapters allows use of 1¼" eyepieces in any 2" focuser or diagonal
The "high-hat" adapter is specially designed with a high rise head to keep Tele Vue Barlows and Powermate amplifiers away from the diagonal mirror.
All models feature brass clamp ring 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
