1.  Target Name/Mount Position: displays the name of the target that telescope is currently pointed to or 

the current mount position. 

•  Zero Position: The position when the mount is turned on. Or the mount is moved to Zero Position 

using “To Zero Position” command; 

•  User Position:  The mount is point to a user defined position, which could be a real sky object or 

just simply due to press an arrow key.

3.  Target Declination: Declination of the target object. 

4.  Right Ascension: Right Ascension of the telescope, or R.A. 

5.  Declination: Declination of the telescope, or DEC. 

6.  Altitude: Altitude of the telescope (degrees vertical from the local horizon - zenith is 90º). 

7.  Azimuth: Azimuth of the telescope (north is 0º, east 90º, south 180º, and west 270º).
