PART III : ALIGNMENT
1. The LCD screen displays “ Choose 1 st Star ” in the first line. Use the scrolling keys to browse
through a list of star names and Press ENTER key to pick the one on the screen as the 1st
alignment star.
2. Now the screen will display “ Point scope to ZZZ.Z’ TT.T’ ”, which means point the telescope
to the direction whose azimuth is ZZZ.Z degree and altitude is TT.T degree. This is also the
direction of the selected 1 st alignment star. Users can use the direction keys on the Syn-
Scan hand control to move the mount to point the telescope to the star and center the star
in the FOV of the finder scope or the red dot finder, and then press ENTER key to proceed
to the next step.

If the telescope has clutches on its axes, user can loosen the clutches to move the mount
manually to point the telescope to the target.
3. Now the screen will display “ Ctr. Star NNNN ”, where the NNNN is the name of the selected
1 st alignment star. The star should have been in the FOV of the telescope. User can use
the direction keys to center it in the eyepiece and then press the ENTER key to proceed to
the next step.
3.5 Alt-Azimuth Mounts using 2-Star Alignment Method
Aligning the 1 st Star:
Aligning the 2 nd Star:
1. The LCD screen displays “ Choose 2nd Star ”. Use the scrolling keys to browse through a list
of star names and Press ENTER key to pick the one on the screen as the 2 nd alignment star.
The mount will then automatically slew and point the telescope towards the 2 nd alignment
star in the sky.
2. After the mount stops, the hand control will give a long beep and will display “ Use dir. keys to
center object ”. The telescope should point rather closely to the 2 nd alignment star (generally,
in the FOV of the finder scope.)
3. Now users can use the direction keys to move the telescope to align with the 2 nd alignment
star. To align, center the 2 nd alignment star in the FOV of the finder scope, and then center
it in the FOV of the telescope’s eyepiece. Press ENTER key to confirm centering of the star
and proceed to the next step. Generally, users can use Rate 5 or 6 to center the star in
finder scope and use Rate 2 or 3 to center the star in the telescope’s eyepiece.
4. The SynScan hand control will now display “ Alignment Successful ”. Press ENTER key to skip
any extra message and complete the alignment process.
Cancellation During Aligning Process:
1. While the mount is slewing during alignment, users may press the ESC key to stop the
mount. The hand control screen will display “ Mount stopped. Press any key… ”
2. Press any key and the SynScan hand control will ask the user to select another alignment
star.
3. Press the ESC key again; the LCD screen will display “ Exit Alignment? 1) YES 2) NO ”. Press
key 1 to exit the alignment process; press key 2 to go back to choose an alignment star.
