Slewing to an Object

Once the desired object is displayed on the hand control screen, you have two options:

Press the INFO Key. This will give you useful information about the selected object such as magnitude, constellation and fascinating facts about many of the objects.

Press the ENTER Key. This will automatically slew the telescope to the coordinates of the object. While the telescope is slewing to the object, the user can still access many of the hand control functions (such as displaying information about the object).

If you slew to an object that is below the horizon, NexStar will notify you by displaying a message reminding you that you have selected an object outside of your slew limits (see Slew Limits in the Scope Setup section of the manual). Press UNDO to go back and select a new object. Press ENTER to ignore the message and continue the slew. The NexStar hand control will only display objects that are below the horizon if the Filter Limits are set below 0º in altitude. See Filter Limits in the Utility Feature section of the manual for more information on setting the filter limits.

Caution: Never slew the telescope when someone is looking into the eyepiece. The telescope can move at fast slew speeds and may hit an observer in the eye.

Object information can be obtained without having to do a star alignment. After the telescope is powered on, pressing any of the catalog keys allows you to scroll through object lists or enter catalog numbers and view the information about the object as described above.

Finding Planets

The NexStar can locate all 8 of our solar systems planets plus the Sun and Moon. However, the hand control will only display the solar system objects that are above the horizon (or within its filter limits). To locate the planets, press the PLANET key on the hand control. The hand control will display all solar system objects that are above the horizon:

Use the Up and Down keys to select the planet that you wish to observe.

Press INFO to access information on the displayed planet.

Press ENTER to slew to the displayed planet.

To allow the Sun to be displayed as an option in the database, see Sun Menu in the Utilities section of the manual.

Tour Mode

The NexStar includes a tour feature which automatically allows the user to choose from a list of interesting objects based on the date and time in which you are observing. The automatic tour will display only those objects that are within your set filter limits. To activate the Tour mode, press the TOUR key on the hand control. The NexStar will display the best objects to observe that are currently in the sky.

To see information and data about the displayed object, press the INFO key.

To slew to the object displayed, press ENTER.

To see the next tour object, press the Down key.

Constellation Tour

In addition to the Tour Mode, the NexStar telescope has a Constellation Tour that allows the user to take a tour of all the best objects within a particular constellation. Selecting Constellation from the LIST menu will display all the constellation names that are above the user defined horizon (filter limits). Once a constellation is selected, you can choose from any of the database object catalogs to produce a list of all the available objects in that constellation.

To see information and data about the displayed object, press the INFO key.

To slew to the object displayed, press ENTER.

To see the next tour object, press the Up key.
