slewing.
5.2.8. Enter R.A. DEC
Here you can go to a target by entering its
R.A. and DEC numbers.
5.3. Sync to Target
This operation will match the telescope's
current coordinates to Target Right
Ascension and Declination. After slew to an
object, press MENU—then scroll to “Sync to
Target” and press ENTER. Follow the
screen to do the sync. Using this function
will re-calibrate the computer to the
selected object. Multiple syncs can be
performed if needed.
“Sync to Target” will only work after “Select
and slew” is performed. Otherwise, the
system may perform incorrectly. You can
change the slewing speed to make the
centering procedure easier. Simply press a
number (1 through 9) to change the speed.
The default slew speed is 64X.
“Sync to Target”
does the same thing as
one star alignment except that you choose
the object to “sync” to. One star alignment
chooses the star/object for you.
