At this point the first alignment star needs to be selected. Press ENTER and the alignment star catalog will appear. 
Scrolling with PREV/NEXT, select a star familiar to you which is near the meridian and press ENTER. Move the 
telescope to the selected star and center it in the eyepiece and press ENTER. At this point polar alignment is 
complete and you may exit by pushing the MODE key. Magellan also offers the option of selecting a second 
alignment star to further correct alignment inaccuracies in the original polar positioning of the telescope. The 
procedure for using the second alignment star is the same as for the first and Magellan will prompt the user with 
display messages.  

If errors occur during the alignment procedure Magellan can detect these based on calculations of expected values. 
For example, if the wrong star is centered during alignment, Magellan will detect that the distance between stars is not 
what should be expected. If this variation exceeds preset limits, Magellan will display the message "Alignment Error 
Check Stars." If this occurs, press ENTER and begin the alignment procedure again. If the alignment is successful a 
number will be displayed next to the "Align" display which gives a relative value of merit for alignment quality (100 is 
perfect as in 100%).  

3. Date

  

The date is required to locate planets and is in Month/Day/Year format. The date can be altered by pressing ENTER 
to select the date function. This causes the cursor to blink on the first date digit. The value of each digit is changed 
and selected by using the keypad. After the last digit of the year is selected pressing ENTER will complete the date 
function.  

4. Encoders...

  

This function is used to select the encoder specifications used on the telescope. The default values may need to be 
changed for high resolution encoders shipped with your telescope. If the standard value of the encoder is different 
due to a change in gear ratios, a note will appear in the installation instructions which will direct you to change this 
ratio setting. Press ENTER to select the Encoder function and change the ratios as needed by using the keypad as in 
previous examples.  

5. Reverse N/S

  

The Reverse N/S menu selection reverses the direction of the telescope in North and South movements (e.g., when 
you press the N key the scope will move South instead of North or up). This is especially useful during some guiding 
applications in imaging and observing. To use the Reverse N/S menu, move the LCD arrow to Reverse N/S menu, 
move the LCD arrow to reverse N/S and press ENTER. If you wish to return the direction commands to the original 
setting, press ENTER again. A check mark to the right side of the display indicates when this function is active 
(reversed).  

6. Reverse E/W

  

The Reverse E/W menu selection reverses the direction of the telescope in East and West movements (e.g., when 
you press the W key the scope will move East). This is especially useful during some guiding applications in imaging 
and observing. To use the Reverse E/W menu, move the LCD arrow to Reverse E/W menu, move the LCD arrow to 
reverse E/W and press ENTER. If you wish to return the direction commands to the original setting, press ENTER 
again. A check mark to the right side of the display indicates when this function is active (reversed).  

7. North Hemi.

  

This function overrides the telescope hemisphere directions. If you activate this function your telescope will perform 
sidereal tracking movements in the direction specified. This will override the internal jumpers for this information. 
Pressing ENTER will toggle the function between North and South setting.  

8. Help...

  

A very brief description of Magellan functions is given by this option. Pressing ENTER will display the help messages 
and the PREV/NEXT keys move the user through this text. Pressing the MODE key will end the help session.
