within the secondary mirror reflection.
When the secondary mirror is correctly
aligned, it will look like Fig. 13 (Note:
The primary mirror is shown out of
alignment).
C. PRIMARY MIRROR ADJUSTMENTS
(114mm & 130mm models only)
If the secondary mirror (Fig. 13, 1) and the
reflection of the primary mirror (Fig. 13, 2)
appear centered within the draw tube (Fig.
13, 3), but the reflection of your eye and the
reflection of the secondary mirror (Fig. 13, 4)
appear off center, you will need to adjust the
primary mirror tilt screws of the primary mirror
cell (Fig. 10, 2). These primary tilt screws
are located behind the primary mirror, at the
lower end of the main tube.
NOTE:
The LightBridge 82mm telescope
does not have primary mirror collimation
screws and is permanantly mounted at the
factory.
