EQ North  

Used to track the sky when the telescope is polar aligned 
in the Northern Hemisphere. 
 

EQ South   

Used to track the sky when the telescope is polar aligned 
in the Southern Hemisphere. 
 

Off 

When  using  the  telescope  for  terrestrial  (land) 
observation,  the  tracking  can  be  turned  off  so  that  the 
telescope never moves. 

 

Tracking Rate

      In addition to being able to move the telescope with the hand control 

buttons, your telescope will continually track a celestial object as it 
moves across the night sky.   The tracking rate can be changed 
depending on what type of object is being observed: 

 

Sidereal 

This  rate  compensates  for  the  rotation  of  the  Earth  by 
moving the telescope at the same rate as the rotation of 
the  Earth,  but  in  the  opposite  direction.    When  the 
telescope is polar aligned, this can be accomplished  by 
moving the telescope in right ascension only.   
 

Lunar 

Used  for  tracking  the  moon  when  observing  the  lunar 
landscape. 
 

   Solar 

Used  for  tracking  the  Sun  when  solar  observing  with 
the proper filter. 
 

 

View Time-Site 

-  Displays the current time and longitude/latitude downloaded from the 

optional CN-16 GPS receiver.  It will also display other relevant time-site information like 
time zone, daylight saving and local sidereal time. Local sidereal time (LST) is useful for 
knowing the right ascension of  celestial objects that are located on the Meridian at that time. 
View Time-Site will always display the last saved time and location entered while it is linking 
with the GPS.  Once current information has been received, it will update the displayed 
information.  If GPS is switched off or not present,  the hand control will only display the last 
saved time and location. 

  

   

User Defined Objects

   - Your telescope can store over 100 different user defined objects in its 

memory  (99  sky  objects  and  9  land  objects).  The  objects  can  be 
daytime  land  objects  or  an  interesting  celestial  object  that  you 
discover that is not included in the regular database. There are several 
ways to save an object to memory depending on what type of object it 
is:
