Occasionally the Primary Mirror must be adjusted. Remove the Barlow Lens

30x Eyepiece, and the Eyepiece Sleave. Look into the Telescope through the
Eyepiec Mount at the Primary Mirror.

Primary Mirror. The reflected image must be centered in the Primary Mirror as
shown in Figure 7 below.

back of the telescope. While  looking through the opening of the Eyepiece
Mount to verify that the reflection is centered in the mirror. Only slight
adjustment should be required. See Figure 7 below.
