Homofocal Rings - to equalize focus positions

Many amateur astronomers use eyepieces from different manufacturers. But each eyepiece has its own position where the image is in focus. The positions of sharp focus can differ. This set of parfocal rings, each 5mm thick, brings your eyepieces and cameras into virtually identical focus.

The advantages in a nutshell:

• equalizes the focus positions for multiple eyepieces
• prevents damage to star diagonals
• achieves the same position for eyepiece and camera
• two clamping screws at a 120° angle
• 1.5mm Hex key included
