PART III : ALIGNMENT
3. The hand control will generate a list of the bright stars within the selected horizontal region.
The list is sorted by the brightness of the star and with the brightest stars at the top of the
list. Users can use the scroll keys to browse the list. An example of the screen display is
shown in Fig. 3.4b.
• Only stars brighter than magnitude 1.5 will appear in the list. If there is no star brighter
than magnitude 1.5 in the selected region, the hand control will display “ No object found
in this region .”
• If multiple bright stars appear in the list, users can identify the names of the stars in
the real sky by matching the azimuth, altitude and magnitude provided by the SynScan
hand control.
• Pick one of the star(s) (Generally the brightest one) as the 1 st alignment star and press
ENTER key to proceed to the next step. Press the ESC key to return to the previous step
(“ Select Region ”).

4. Now the screen will display “ Point scope to RR ZZ.Z’ TT.T’ ”, which means point the telescope
to RR region, the exact azimuth is ZZ.Z degree and the exact altitude is TT.T degree. Users
can use the direction keys on the SynScan hand control to move the mount and point the
telescope to the 1 st alignment star selected in the previous step. Center the 1 st alignment
star in the FOV of the finder scope or the red dot finder, and then press ENTER key to pro-
ceed to the next step.
PART III : ALIGNMENT
5. Now the screen will display “ Ctr. to eyepiece.. ” and 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.
Aligning the 2 nd Star:
Cancellation During Aligning Process:
1. If the 1 st alignment star is not a planet, the LCD screen will display “ Choose 2 nd Star ”; other-
wise, it will display “ Choose 1 st Star ”.
2. 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.
3. After the mount stops, the hand control will display the name of the selected 1st star on line
1 and “Ctr. to eyepiece..“ on line 2. Now the telescope should point rather closely to the 2
nd
alignment star (generally, in the FOV of the finder scope).
4. Now users can use the direction keys to move the telescope to align with the 2 nd alignment
star. That is, 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 the 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.
5. If the 1 st alignment star is not a planet, the SynScan hand control will now display “ Align-
ment Successful ”. Press ENTER to complete the alignment process.
6. If the 1 st alignment star is a planet, the SynScan hand control will display “ Choose 2 nd Star ”.
Repeat from Step 2 to complete the alignment process.
1. While the mount is slewing in alignment process, 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.
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.
