Collimation Ring CR140
The COLLIMATION RING has a direct fit to the 140mm f/6.5 APO triplet objective lens via fine thread. If you’re building your own telescope you need to retain the ability to collimate the lens so we strongly suggest purchasing the collimating ring together with the lens in cell.
