5.1.7. User Objects

It can store up to 60 used entered objects, including comets.

5.1.8. 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. 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.

5.3.3. Set Anti-backlash

All mechanical gears have a certain amount of backlash or play between the gears. This play is evident by how long it takes for a star to move in the eyepiece when the hand control arrow buttons are pressed (especially when changing directions). The Go2Nova anti-backlash feature allows user to compensate for backlash by inputting a value which quickly rewinds the motors just enough to eliminate the play between gears.

To set the anti-backlash value, scroll down and select “Set Anti-backlash”
