Description

Springs for Common Newtonians 8", 10", and 12" Primary

Part: CNspr

Fits: Many Newtonian models (8", 10", 12") except 16"

Primary mirror springs as supplied by the factory can sag from the weight of the mirror cell. Our 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.

Notes:
  1. These springs will fit if your primary mirror cell looks like the cell depicted in the photos.
