5.5.2. One Star Align
From the main menu, select “Align”. Select “One Star Align” and press ENTER. A list of bright align stars that are above the horizon is computed based on your local time and location. These stars are listed alphabetically. Use ▲ or ▼ button to select a star and press ENTER. The mount will slew to it automatically. Use ◄ ► ▲ or ▼ key to center the object in your eyepiece. Press SPEED button to change the slew speed if needed. Then press ENTER to complete the alignment. Or press the BACK key to cancel the process.
If you have a very good initial setup, one star alignment should be sufficient for good GOTO accuracy. To increase the accuracy you may choose to do two star alignment.
5.5.3. Two Star Alignment
Two star alignment will increase the GOTO accuracy of the mount. It is suggested to do two star alignment after one star alignment. Select “Two Star Align” in the Align menu. Use ▲ or ▼ button to select a star and press ENTER. The mount will slew to it automatically. Use ◄ ► ▲ or ▼ key to center the object in your eyepiece. Press SPEED button to change the slew speed if needed. Then press ENTER to complete the alignment. After you finish the first star, the system will prompt you to choose the second star. Repeat the process to finish the second star alignment. An “Align OK!” screen will show briefly. To obtain a better alignment effect, it is suggested to choose two align stars far apart.
“Two Star Align” result will be overridden if “Solarsys Align” ,“One Star Align” or “Sync. to Target” is performed after “Two Star Align.”
