the rotation of the knob just to make sure
you've hit the exact focus point. You will have
to readjust the focus when aiming at subjects
of varying distances, or after changing
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.
(Please be patient turning the focus knob.
There are about 11 full turns from one end to
the other when using the larger/coarse tuning
knob).
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
The
supplied
finderscope comes with a quick-release
bracket. The dual-ring bracket has six
collimating screws for precise alignment with
the main scope optics. The quick-release
bracket slips into a dovetail mounting shoe at
the rear of the scope during use.
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 six
collimation screws to center the object in the
finderscope. Now, objects located first with
the finderscope will be centered in field of
view of the main telescope.
