Update standard telescope springs with Farpoint Collimation Spring Kit - Zhumell Z12 to keep the primary mirror in optimum alignment.

Replace weak stock springs with Farpoint springs to create positive collimation adjustments and hold collimation. Standard collimation locking screws are no longer needed, which saves a step in the collimation process and also makes the locking screw threaded holes available for other accessories.

Compatible with Zhumell 12" Z12 and many other similar Dobsonians. Also fits most GSO 10" Dobsonians.
