The original springs often used in standard mirror cells sometimes provide a counter pressure that is too low for a stable collimation. The TS stainless steel coil springs are stronger and hold even heavier mirrors e.g. with 12″.

Our TS counter pressure springs fit e.g. to:
— All GSO Newtonian and Dobsonian telescopes
— All ICS Dobsonians with red OTA
— Skywatcher Newtonian and Dobsonians
— Meade Newtonians and Dobsonians
… and many more
