PRIMARY MIRROR ADJUSTMENTS
If the
secondary mirror
(fig. 7, #1) and the reflection of the
primary mirror
(fig. 7, #2) appear centered within the
draw tube
(fig. 7, #3), but the reflection of your eye and the reflection of the
secondary mirror
(fig. 7, #4) appear off center, you will need to
adjust the
primary mirror tilt screws
(fig. 3, #2) of the
primary
mirror cell.
These
primary tilt screws
are located behind the
primary mirror
, at the lower end of the
main tube.
To adjust the
primary mirror tilt screws
(fig. 3, #2), first turn by
several turns, the
primary mirror cell lock knobs
(fig. 3, #3)
that are next to each
primary mirror tilt screw
. The three
primary mirror cell locking screws
are slotted head screws
on the EclipseView 114 models. Then by trial-and-error, turn the
primary mirror tilt knobs
(fig. 3, #2) until you develop a feel for
which way to turn each knob to center the reflection of your eye.
Once centered, as in
Figure 5
, turn the 3
primary mirror cell
locking screws
(fig. 3, #3) to re-lock the tilt-angle adjustment.
(114mm Models Only):
NOTE: The EclipseView 82mm telescope does
not have primary mirror collimation screws and is
permanently mounted at the factory.
