On most refractors, the eyepiece focusers can be replaced with more stable OAZs.

Most refractors allow for replacement of the focuser with a more stable focuser.

Although we adjust each focuser very precisely before shipping, some stargazers prefer a higher-quality, more sensitive focusing system.

Some focusers can be replaced directly; others require an adapter. We will be happy to replace the focuser free of charge if you purchased the telescope and the focuser from us.
