One-Star Alignment:

Step 2: After you select this option, you will be prompted to select a target star. The software will select a star that 

is very visible in the night sky. If you happen to know of a star you can see with the naked eye, you can choose it by 

pressing the up and down arrow keys and then selecting it with the center key (22). In most cases, you will want to 

select the first option presented to you. Do so by pressing the center key (22).

Step 3: The telescope will now slew to that star and will prompt you to center it in the field of view, which you can do 

by using the arrow keys. The star you’re focusing on is the brightest star in the region your telescope is pointing at. 

When the star is centered, confirm the position with the center key (22). The telescope is now aligned.

Two- and Three-Star Alignment:

The procedure is similar to one-star alignment. The only difference is that you’ll have to repeat steps 2 and 3 twice 

or thrice depending on the type of alignment you’ve chosen.

Note: If you have aligned the telescope, don’t move it manually. Use the arrow keys on the handbox to make 

adjustments. If you do move it manually or change the tripod orientation, the telescope has to be realigned.

5. Further Adjustment:

Target Sync:

With this method, you can further improve the alignment of the telescope. After slewing to a star target you know, 

you can center the object precisely in the field of view. Press the center key (22) and select ‘Telescope Align’, then 

‘Target Sync’. The telescope will align to that target and have more precise positioning for further targets you want 

to observe.

Backlash Correction:

You can improve the precision of the telescope by training the backlash correction of the axis. This must be done 

separately for each axis and is not necessary for most cases.

Simply go to the main menu by pressing the center key (5) and select ‘Telescope Align’ and then ‘RA BKlash Corr.’ 

to adjust the right ascension axis (horizontal axis) or ‘DEC BKlash Corr.’ to adjust the declination axis (vertical axis). 

Then follow the on-screen instructions.
