PART III : ALIGNMENT
3. Now users can use the direction keys to move the telescope to align with the 1
st
alignment
star. That is, center the 1
st
alignment star in the FOV of the nder scope, and then center
it in the FOV of the telescope’s eyepiece; press ENTER key to conrm centering of the star
and proceed to the next step. Generally, users can use Rate 5 or 6 to center the star in the
nder scope and use Rate 2 or 3 to center the star in the telescope’s eyepiece.
4. If the user has chosen 1-Star Alignment method before, the SynScan hand controller will
now display “Alignment Successful”. Press ENTER to complete the alignment process.
5. If the user has chosen 2-Star Alignment or 3-Star Alignment before, the SynScan hand
controller will then proceed to the next step.
The operation is the same as that of Aligning the 2
nd
Star.
1. While the mount is slewing during the alignment, users may press the ESC key to stop the
mount. The hand controller screen will display “Mount stopped. Press any key…”
2. Press any key and the SynScan hand controller will ask the user to select another align-
ment 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.
1. Find the brightest stars in the current sky with naked eyes, and estimate its horizontal re-
gion (orientation).
2. The hand controller displays “Select Region”. Use the scroll keys to pick one of the eight
regions shown in Fig 3.4a, which matches the horizontal region of the brightest star. Press
ENTER to conrm selection and proceed to the next step.

1. Again, the SynScan hand controller asks the user to choose and align a 2
nd
alignment star.
The operation is the same as that of aligning the 1
st
alignment star.
2. If the user has chosen 2-Star Alignment before, the SynScan hand controller will display
“Alignment Successful” after conrmation of centering the 2
nd
alignment star.
3. Two seconds later, the LCD screen will display the polar-alignment offset of the mount. The
“Mel” value is the offset in elevation, and the “Maz” value is the offset in azimuth.
4. If the user has chosen 3-Star Alignment before, the SynScan hand controller will then pro-
ceed to the next step.
