Collimation CORRECT COLLIMATION: The properly collimated (aligned) mirror system in the Meade EclipseView telescope assures the sharpest images possible. This occurs when the primary mirror and secondary mirror are tilted so that the focused image falls directly through the center of the focuser draw tube. To inspect the view of the mirror collimation, look down the focuser draw tube with the eyepiece removed. The edge of the focuser drawtube (fig. 5, #1), will frame the reflections of the primary mirror with the 3 mirror clips (fig. 5, #2), the secondary mirror (fig. 5, #3), the spider vanes (fig.5,#4), and your eye (fig.5,#5). Properly aligned, all of these reflections will appear concentric (i.e., centered) as illustrated in Figure 5. Any deviation from the concentric reflections will require adjustments to the secondary mirror assembly (fig. 4) and/or the primary mirror cell (fig. 3). Figure 5 41 40

Collimation
CORRECT COLLIMATION:
The properly collimated (aligned) mirror system in the
Meade EclipseView
telescope assures the sharpest
images possible. This occurs when the primary mirror
and secondary mirror are tilted so that the focused image
falls directly through the center of the focuser draw tube.
To inspect the view of the mirror collimation, look down
the focuser draw tube with the eyepiece removed.
The edge of the
focuser drawtube
(fig. 5, #1), will frame
the reflections of the primary mirror with the
3 mirror
clips
(fig. 5, #2), the
secondary mirror
(fig. 5, #3), the
spider vanes
(fig. 5, #4), and
your eye
(fig. 5, #5). Properly
aligned, all of these reflections will appear concentric
(i.e., centered) as illustrated in
Figure 5
. Any deviation
from the concentric reflections will require adjustments
to the
secondary mirror assembl
y (fig. 4) and/or the
primary mirror cell
(fig. 3).
