Collimation
EclipseView76 Models Only
CORRECT COLLIMATION:
The properly collimated (aligned) mirror system in the
Figure 5
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).
