number of the object you wish to select and press ENTER. The
telescope will automatically retrieve and display the coordinates
before slewing to the object.
Save Sky Object:
Your telescope stores celestial objects to its database by saving its
right ascension and declination in the sky. This way the same object
can be found each time the telescope is aligned. Once a desired
object is centered in the eyepiece, simply scroll to the "
Save Sky Save Sky Save Sky Save Sky
Obj"
Obj" Obj"
Obj"
command and press ENTER. The display will ask you to enter
a number between 1-99 to identify the object. Press ENTER again to
save this object to the database.
Save Database (Db)
Object:
This feature allows you to create your own custom tour of database
objects by allowing you to record the current position of the telescope
and save the name of the object by selecting it from any one of the
database catalogs. These objects then can be accessed by selecting
GoTo Sky Object.
Enter R.A. - Dec:
You can also store a specific set of coordinates for an object just by
entering the R.A. and declination for that object. Scroll to the
"
Enter RA Enter RA Enter RA Enter RA- - - -DEC " DEC " DEC " DEC "
command and press ENTER. The display will
then ask you to enter first the R.A. and then the declination of the
desired object.
Save Land Object:
The telescope can also be used as a spotting scope on terrestrial
objects. Fixed land objects can be stored by saving their altitude and
azimuth relative to the location of the telescope at the time of
observing. Since these objects are relative to the location of the
telescope, they are only valid for that exact location. To save land
objects, once again center the desired object in the eyepiece. Scroll
down to the "
Save Land Obj Save Land Obj Save Land Obj Save Land Obj
" command and press ENTER. The
display will ask you to enter a number between 1-9 to identify the
object. Press ENTER again to save this object to the database.
To replace the contents of any of the user defined objects, simply save a new object using
one of the existing identification numbers; the telescope will replace the previous user
defined object with the current one.
Get RA/DEC - Displays the right ascension and declination for the current position of the
telescope.
Goto R.A/ Dec
- Allows you to input a specific R.A. and declination and slew to it.
To store a set of coordinates (R.A./Dec) permanently into the database, save it as a User
Defined Object as described above.
