What is a periodic error?

Periodic error (PE) is the name for the inevitable small mechanical errors that occur in the drive gearing as the scope is tracking during long-exposure imaging. Since these errors are part of the scope’s drive and are predictable, they can be evaluated and counteracted to improve tracking for astro-imaging.

What is periodic error in a telescope mount?

What is Periodic Error? Periodic Error is a small mechanical error in the accuracy of the tracking in a motorized mount that results small movements of the target that can spoil long-exposure images, even if the mount is perfectly polar-aligned and appears to be tracking perfectly in short tests.

What causes periodic error?

Periodic error is generally caused by imperfect gears or mis-aligned bearings. Many telescope drives in the amateur market typically use a motor driving a worm gear via a gear box. The worm gear meshes with a spur gear that is directly attached to the right ascension axis of the mount.
