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. When mounted in Alt-
Az mode, the telescope must make corrections in both R.A. and
declination.

Used for tracking the moon when observing the lunar landscape.
Lunar
Used for tracking the Sun when solar observing using a proper solar filter.

User Defined Objects - The NexStar can store over 100 different user defined objects in its memory. 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:
Save Sky Object: The NexStar 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 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.
Save Land Object: The NexStar 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" 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.
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-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.
GoTo Object: To go to any of the user defined objects stored in the database, scroll down to either GoTo Sky
Obj or Goto Land Obj and enter the number of the object you wish to select and press
ENTER. NexStar will automatically retrieve and display the coordinates before slewing to the
object.
To replace the contents of any of the user defined objects, simply save a new object using one of the existing identification
numbers; NexStar will replace the previous user defined object with the current one.

Your NexStar mount includes a Camera control feature that allows you to remotely take a series of exposures using your digital
SLR (DSLR) camera body. The camera feature comes with an easy to use Camera Wizard that allows you to save a list of as
many as nine targets. Then with a DSLR attached or piggyback mounted to your telescope, NexStar will automatically slew to
the specified targets and take an exposure of each one.
