This popular eyepiece adapter allows 1.25" eyepieces and accessories to be used in 2" focusers, diagonals and barlows. It includes a brass compression ring that restrains the eyepiece and prevents marring of the eyepiece barrel by the metal set-screw. It is precision machined from aluminum and anodized black.
Threaded to accept standard 48mm filters so you can use your 1.25" eyepieces with your 2" filters (be careful not to let the eyepiece barrel hit the filter though).
