Revelation 1.25" Parfocalising Rings
Ref: FP501
£19.99
A set of four aluminium parfocalising rings for setting accurate focus on any 1.25" eyepiece, barlow or camera nosepiece. These useful rings simply slide on the chrome 1.25" eyepiece barrel allowing you set them at a precise distance so all your eyepieces focus at the same point. This makes changing eyepieces much easier without refocusing, this is especially useful when imaging with webcams where you need to locate the object with an eyepiece then swap for the camera, now you can do this without changing focus.
All four precision machined rings have two Allen type grub screws to secure them on the eyepiece barrel, an Allen key and full instructions are provided.
Please note: Eyepiece not included
