Omegon Parfocal Locking Rings 1.25 inch (set of 3)

Omegon Parfocal Shims 1.25 inch (Set of 3): Eyepieces at the Same Focus

Parfocal means that different eyepieces are in focus at the same focus position. Without rings, you have to refocus after each eyepiece change, which takes time and disrupts the image. With the rings, you set these differences once.

The set includes three 5mm thick aluminum rings. You place them between the eyepiece or camera and the focus adapter, and secure them with two set screws at 120 degrees. A 1.5mm Allen key is included.

Features

• Three aluminum rings of 5 mm
• For 1.25 inch eyepieces and cameras
• Two clamping screws per ring at 120 degrees
• 1.5 mm Allen wrench included

Compatibility

Especially useful in astrophotography, where refocusing after an eyepiece change can shift the framing. For 2-inch eyepieces, there is a separate set.
