6. When you look through the viewfinder, you
will notice that the observation target is not
in the center of its field of view, but shifted
off to the side instead. Use the three knurled
screws to adjust the viewfinder until the
center of its field of view matches that of the
telescope. To do this, keep loosening one or
two of the screws while you tighten the
other(s). You will probably have to repeat this
several times. Keep looking into the
viewfinder to verify that the observation
target is moving toward the center of the
field of view.
7. If adjustment of the three knurled screws is
not enough, you will have to loosen the two
knurled screws again on the viewfinder
bracket and correct the viewfinder's
orientation before returning to the viewfinder
alignment instructions described in step 6.
8. After orienting the viewfinder, all three
knurled screws should be gently tightened
again so that the viewfinder doesn't
inadvertently shift in its bracket. Finally,
check one last time to make sure that the
viewfinder and the telescope show the same
observation target in the center of their fields
of view.
View through the telescope (top); view through the
viewfinder: misaligned (center) and aligned (bottom).
