How to use
1.
Movingthe telescope
Move the telescope by using the joystick type controller, which is connected to
the main body. Depending on the degree of inclination of the stick, the telescope
can be moved at a sidereal rate speed of around 2x18x, 64x, 128x, 300x, 800x.
For example, if the joystick is tilted to the right, the telescope will turn to move to
the right (Fig. 14),if it is tilted forward, the telescopewill turn to move downwards.
(Fig. 15)
(In erect-image mode. By changing mode, movement can be changed. Refer to
the later MODE CHANGE).

When moving at a low speed, move the joystick back and forth, rather than
keeping a steady tilt of the joystick.
2.
Adjusting finder scope
It is not easy to find a target star, since the telescope uses high magnification
power. Therefore, to facilitate your search for a star, use the finder scope which
has a lower magnification. Be sure that the field of view of the telescope is
aligned with that of the finder scope.
2-1 Pulldown the mirror shift lever. (Fig. 17)

2-3 While looking into the eyepiece, move the telescope so the top of a utility
pole or tower, approximately
500
meters away, comes into the center of the field
of view. (Fig. 20). When an object comes into the center of the sight, turn the
focusing knobto achieve focus. (Fig. 21).

In this case, the image in the eyepiece (diagonal mirror) appears reversed side
to side from that which is actually observed by the naked eye.When the mode of
the joystick is in the Erect-Image Mode, an image that is reversed side to side
from the tilt direction will move. (Refer to the page of Erect-Image Mode)

To alignthe field of view of the finder scope and eyepiece together, look into
the finder scope steadying the telescope (Fig. 22). Adjust the finder scope by
turning the three finder adjustment thumbscrews to bring a target object into the
center of the cross hair line, which is viewed through the eyepiece (diagonal
mirror). (Fig.
23)
Potatethe ac!i~lstlnel\ttllil~nl)zr~

In this case, an image that is seen in the finder scope appears in the same
orientation as is seen by the naked eye.
2-5 When a target object comes into the center of the cross hair lines in the
finder scope while looking into the eyepiece (diagonal mirror), finder scope
adjustment is complete.
This procedurewill not be required again unless the finder scope or telescope is
moved or the finder scope adjustment thumbscrews will not move. The three
adjustment thumbscrews of the finder scope are designed to be a push-in and
pull-up screw. Do not try to adjust them at the same time, but minutely adjust
each screw individually.
