Instructions / Assembly

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.
