Pressing any of the other catalog keys (M, CALD, NGC, or STAR) will display a blinking cursor below the name of the
catalog chosen. Use the numeric key pad to enter the number of any object within these standardized catalogs. For example,
to find the Orion Nebula, press the "M" key and enter "042".
Slewing to an Object
Once the desired object is displayed on the hand control screen, choose from the following options:
Press the INFO Key. This will give you useful information about the selected object such as R.A. and
declination, magnitude size and text information for many of the most popular objects.
Press the ENTER Key. This will automatically slew the telescope to the coordinates of the object.
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
Your telescope can locate all 8 of our solar systems planets plus the 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.
Tour Mode
The telescopes include 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 (see Filter Limits in the Setup Procedures section of the manual). To activate the Tour mode, press the TOUR key (6)
on the hand control. The hand control 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 Up key.
Constellation Tour
In addition to the Tour Mode, your telescope has a Constellation Tour that allows the user to take a tour of all the best objects
in each of the 88 constellations. 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.
