It is better to carry out most of this procedure
during the daytime.
By adjusting (tighten or loosen) the 3 adjust-
ment screws on the finder bracket, the direction
of the finder can be changed.
For example, by tightening the adjustment screw
on the top and loosening the two adjustment
screws on the bottom, the finder can be turned
to face upwards (see the picture below for
reference).
4) When the object seen through the main tube
has been centered on the crosshair of the
finder, slowly tighten the adjustment screws
equally to fix the finder.
5) The alignment of the finder scope has been
completed. Please make sure that the axis of
the scope is not out of alignment before star
observation.
1) Aim the telescope at a small object that is
about several km away, such as a chimney top
or tip of an antenna.
2) Center the object in the eyepiece.
3) After that, look at the object with the finder
scope this time. If the object has already been
centered on the crosshair, alignment of the
finder is not necessary.
If it is not focused, slowly turn the focusing
knob until the object comes into focus.

Aligning the Finder Scope
●What is a finder scope?
If you try to find a star with a telescope from the very beginning, it is very hard to catch the
target astral object due to high-powers and narrow field of view of the telescope. The finder has
a lower-powers and wider field of view compare to the main telescope and it is easier to find the
positional relations between the stars. You can see the reticle in the center field of the finder
and set the target astral object at this cross point.In order to smoothly introduce the target
astral object to the main tube through the finder scope, the finder must be collimated (aligned)
with the telescope first. Please align the optical axis of the finder scope through the following
steps before observing.
