After determining the home position of your telescope, press the key to display the
interactive dialog box on the screen. The dialog box asks you if you enter

SCOPE MODE

.

Choose OK with the or key and press the key.

The star chart in

SCOPE MODE

appears on the screen. The concentric target circles in the

center of the star chart indicate due west. (The target circles indicate due east in the
southern hemisphere.)

The SXP mount starts tracking at the celestial rate from that point and now the Go-To
slewing will accurately bring a target object in the finder scope's field of view. You need to
proceed to star alignment to set the pointing accuracy of your telescope.

After this,

CHART MODE

and

SCOPE MODE

will switch over each time you press the key

while the star chart is displayed on the screen. Its status is displayed at the upper left on
the screen. Pressing the key in

CHART MODE

will ask you to proceed to the Go-To

slewing.

The star alignment matches celestial coordinates of stars memorized as location information in the STAR BOOK TEN with positions of stars that
can actually be seen in the sky. The location information is identified with a star and this paring is called “getting an alignment point”.

CHART MODE

and

SCOPE MODE

can switch over each time you press the key.

CHART MODE

is independent from the movements of your telescope. The top and bottom of the

screen are highlighted in blue in

CHART MODE

. With no linkage to the telescope, scrolling of

the chart is quick and easy with the • • • direction keys. Go-To slewing is
readily available with the command keys. Additionally, you can look for a target directly on the
star chart in this mode.

The screen will turn to

SCOPE MODE

as soon as the telescope gets to the target.
