ORION SKYQUEST XX-SERIES NEWTONIAN

We offer knobs for the Orion SkyQuest XX-series secondary only, since the primary already has factory knobs. The secondary assembly can have two different configurations. Select the correct configuration for your telescope from the list below by using our photos and guidelines. Price is for a complete set of knobs.

A. Knobs for Orion SkyQuest XX-Series Primary

The Orion SkyQuest XX-series primary is equipped with factory collimation and lock knobs. Although the lock knob is small, its proximity to the collimation knob prevents replacing it with a larger knob. Therefore we do not offer replacement primary collimation or lock knobs.
