TeleVue's all-brass "Equalizer" 1.25" adapter, with brass compression ring and captured thumbscrew, ups the weight of a 1.25" eyepiece to equal the heavier 2" ones, making balance of the scope a LOT easier. It also makes a lot of 1.25" eyepieces come to focus close to the 2" eyepieces.

• Solid Brass construction
  Safety undercut groove to provide safe retention in a focuser or diagonal.
  Extended top provide safety for insertion of longer accessories (especially TeleVue's 1.25" eyepieces with 2" skirts) and supports most 1.25" eyepieces better.
  Brass retention ring internally prevents marring of the barrels of eyepieces or accessories inserted in the adapter.
  Best support for 1.25" eyepieces with 2" skirts.
  12 ounce weight helps balance eyepieces to provide more constant weight in focuser, making balancing easier.
  12.5mm height

These adapters allows use of 1.25" eyepieces in any 2" focuser or diagonal. All models feature brass clamp ring for secure, no-mar locking and safety undercut. Note: TeleVue purposely does not put 2" filter threads in 2" to 1.25" adapters. The reason is to avoid your getting upset when you insert a 1.25" Barlow and it crunches your expensive 2" filter. Safety first. 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. The heavy solid bronze version, the "Equalizer", adds 12-ounces to help equalize the weight when switching from heavy 2" eyepieces to light 1.25" eyepieces. Features exclusive lower end anti-reflection angle that prevents reflection back to the objective.
