(3, Fig. 14), the spider vanes
(4, Fig. 14), and your eye (5, Fig. 14).
Properly aligned, all of these 17 reflections will appear concentric
(i.e., centered) as illustrated in Fig. 14.
Any deviation from the concentric reflections will require adjustments to the diagonal assembly and/or the primary mirror cell (Fig. 11).
B. DIAGONAL HOLDER ADJUSTMENTS
If the diagonal mirror (1, Fig. 15) is centered
familiarize yourself with the following collimation procedure, so that you will recognize a properly collimated instrument and can adjust the collimation yourself, if necessary.

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. 14), will frame the reflections of the primary mirror with the 3 mirror clips (2, Fig. 14), the diagonal mirror
