finder and move the upper portion of the dot finder
by holding its front end so that dot finder is parallel
to the telescope tube roughly. Tighten the alignment
clamp knob.
Insert an eyepiece with low magnification into the
②
eyepiece adapter on the focuser of the telescope.
Choose a conspicuous target in the distance and point the telescope for it to get the
target in the field of view of the eyepiece. Place the target in the center of the field of view.
Turn on the red dot by turning the brightness control dial. The intensity of the
③
brightness can be varied freely and stop turning the dial at a proper brightness.
*The brightness control dial turns off when the white dot mark on the dial goes back
to directly overhead the white dot mark on the side of the dot finder.
Confirm that a red dot is spotted just above the aiming needle on the bottom of the
④
finder's field of view which is aligned with the white guideline as shown in the figure.
*The red dot can be seen clearly with a target in the far-off distance if your eyesight
is good enough without spectacles. The red dot may not be seen as a tight point
image or blurred if you have weak eyesight.

H i n t
Use the XY red dot finder so that its red dot is in the center of the field of view.
The red dot is used for sighting regardless of a position of view as long as it can be seen in the dot finder's field of view.
However, sighting from the corner is uncomfortable and it makes you difficult to locate the red dot. It may result in inaccuracy
of the dot finder. If you are unable to find the red dot, try to sight from a position close to the white guideline.
