About this product

Model:  bk_newtonian_springs

Bobs Knobs Springs for GSO manufactured Newtonian/Dobsonian telescopes with  8”, 10”, and 12” primary mirrors.

Some telescope owners find the factory-fitted primary mirror springs are a little too weak to maintain precise collimation in some circumstances. 

These Bobs Knobs stainless steel replacement springs are stronger, so provide more support. 

NOTE: We recommend your telescope's mirror locking screws remain in place for additional control.
