Take the time to familiarize yourself with the following collimation procedure, so That you will recognize a properly collimated instrument and can adjust the collimation yourself, if necessary.
A. CORRECT COLLIMATION
The properly collimated (aligned) mirror system in the Polaris 114
To inspect the view of the mirror collimation, look down the focuser drawtube with the eyepiece removed. The edge of the focuser drawtube (1, Fig.13), will frame the reflections of the primary mirror with the 3 mirror clips (2, Fig. 13)
Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
