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. When mounted in Alt- Az mode, the telescope must make corrections in both R.A. and declination.
Lunar Used for tracking the moon when observing the lunar landscape.
Solar 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
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
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
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.
Camera –
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.
Connecting a Camera to the NexStar Mount
Your NexStar mount has a camera control port that allows you to connect your camera using the supplied Shutter Release Cable and a firing cable for your model of camera (not included). To connect you camera:
1.Attach the phone jack end of the supplied cable into the camera port on the base of the mount.
2.Plug the 2.5mm mono jack end of your user supplied firing cable into the Shutter Release Cable.
3.Plug the firing cable into the electric cable release port for your model of camera.
