eyepieces. Turn the fine tuning knob for finer
adjustments.
If you have trouble focusing, rotate the focus
knob counterclockwise as far as it will go.
Now look through the eyepiece while slowly
rotating the focus knob clockwise. You should
soon see the point at which focus is reached.
Try to practice this during daytime by aiming
the main telescope tube at a land-based
target at least 200 yards away (e.g. A
telephone pole or building).
Aligning Finderscope
If you use a finderscope with Versa
TM
108,
you need to align the finderscope with the
main telescope tube.
First, look through Main Telescope Tube and
establish a well-defined target (see focusing
telescope section). Tighten all lock knobs of
your mount (Declination, Latitude, Right
Ascension, and Horizontal Axes) so that
telescope’s aim is not disturbed. Then look
through the finderscope and adjust the each
finderscope adjustment screw until the
crosshairs of the finderscope are precisely
centered on the same object already centered
in Main Telescope Tube’s field of view. Now,
objects located first with the finderscope will
be centered in field of view of the main
telescope.
