4.3.4. Initial Star Alignment

A simple star alignment/synchronization can be performed to improve the GOTO accuracy.

To perform “One Star Align,” press MENU button, scroll down to “Align”, select “One Star Align” and press ENTER. The screen will display a list of bright objects for you to select from. Select an object using ▲ or ▼ key. Then press ENTER. After the mount slews to the target, use the arrow keys to center it in your eyepiece. Then press ENTER. (More align details in 5.6)

An alternate way is to perform “Sync to Target.” Press the MENU button, select “Select and Slew” and press ENTER. Browse over the catalogs and select an object, such as “Stars” Æ“Named stars” Æ140 (Polaris), and press ENTER. After the mount slews to Polaris, press the MENU button, scroll down to “Sync. To Target”, follow the on-screen instruction to center Polaris and press ENTER. You may need to use the number keys to change the slewing speed to make the centering procedure easier.

4.3.5. Go to the Moon

After performing these set-ups the mount is ready to GOTO and track objects. One of the most common objects is the Moon.

To slew to the Moon press the MENU button. Select “Select and Slew” by pressing the ENTER button. Select “Planets, Sun, Moon”, and use the ▲ or ▼ buttons to select Moon. Press ENTER. The telescope will automatically slew to the Moon and lock on it. It will automatically begin to track once it locks on. If the Moon is not centered in your eyepiece, use the arrow keys to center the Moon. Or for better performance use “Sync to Target.”
