Product description

Primary mirror springs as supplied by the factory can sag from the weight of the mirror cell. These stainless steel replacement springs are stronger and provide adequate support to maintain primary mirror collimation.

We recommend that the mirror locking screws remain in place for additional control.

The manufacturer Bob's Knobs supplies various collimation screws for Schmidt-Cassegrain, Ritchey-Chrétien and Newton telescopes.

The selection includes screws for primary and secondary mirrors for optics between 5" and 16". In addition, Bob's Knobs offers mounting screws for various mounts from Celestron (CGE, CGE Pro, NexStar), Losmandy (GM-8, G-11) and TeleVue (Gibraltar).

Please refer to the respective specifications and technical data to find the right screws for your model!
