To inspect the view of the mirror

collimation, look down the focuser draw

tube 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 secondary mirror (3, Fig. 14),

the spider vanes (4, Fig. 14), and your

eye (5, Fig. 14). Properly aligned, all of

these reflections will appear concentric (i.e.,

centered) as illustrated in Fig. 14.
Any deviation from the concentric reflections

will require adjustments to the secondary

mirror assembly and/or the primary mirror

cell (Fig. 12).
B. SECONDARY MIRROR HOLDER

ADJUSTMENTS
If the secondary mirror (1, Fig. 15) is centered

in the draw tube (2, Fig. 15), but the primary

mirror is only partially visible in the reflection

(3, Fig. 15), one or more of the 3 Phillips-

head secondary mirror collimation screws

need adjusting. First, unthread each of

the secondary mirror collimation screws

slightly to the point of where you can tilt

the secondary holder from side-to-side. By

Looking at or near the

Sun will cause irreversable damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
