5.1.6. Constellations
This catalog consists of 88 modern constellations with their names. They are listed alphabetically. A
list is attached in Appendix E.
5.1.7. Enter R.A. DEC
Here you can go to a target by entering its R.A. and DEC numbers.
5.2. Sync to Target
This operation will match the telescope's current coordinates to Target Right Ascension and
Declination. After slewing 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. This operation is most useful to find a faint star or nebula near a
bright star.
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 align” chooses the star/object for you. “Sync to Target” operation will override any
previously performed “Two Star Align” operation.
