Owner's of the Celestron Telescope NexStar HC gave it a score of 0 out of 5. Here's how the scores stacked up:

1.
Press the INFO Key
. This will give you useful information about the selected object such as R.A. and
declination, magnitude and most importantly, altitude above the horizon. (If a star alignment has not yet been
performed, the altitude will not be displayed).
The speed at which information scrolls across the hand control display can be changed while the information is being
viewed:
•
Hold down the “1” key to speed up the scroll speed.
•
Hold down the “4” key to slow down the scroll speed.
•
Hold down the “7” key to freeze the information on the display.
2.
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 very 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, press the
UNDO key. Pressing any of the catalog keys allows you to scroll through object lists or enter catalog numbers as described
above. However, information such as R.A. and declination of planets and altitude above the horizon will not be displayed
unless the telescope is first properly aligned.
Tour Mode
The NexStar includes a tour feature which automatically allows the user to choose from a list of interesting objects based on
the month in which you are observing. The Tour mode is activated by pressing the TOUR key (6) on the hand control. Once
activated, simply use the scroll keys to select the current month and press ENTER. The NexStar will display from a list of
the best objects to observe based on the month entered.
•
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.
When going through any of the object catalogs in the database, you can easily find out which objects are above the horizon
and visible simply by pressing the INFO button when the desired object is displayed. This will display the objects altitude
above the horizon based on the date and time entered. Pressing the UP button once will display any scrolling text associated
with that object. The scrolling text can be viewed even if a star alignment has not been performed.

The NexStar has four direction buttons in the center of the hand control which control the telescope motion in altitude (up
and down) and azimuth (left and right). The telescope can be controlled at nine different speed rates.
Rate Button
Pressing the RATE key (11) allows you to instantly change the speed rate of the motors from high speed slew rate to precise
guiding rate or anywhere in between. Each rate corresponds to a number on the hand controller key pad. The number 9 is
the fastest rate (4º per second, depending on power source) and is used for slewing between objects and locating alignment
stars. The number 1 on the hand control is the slowest rate (1x sidereal) and can be used for accurate centering of objects in
the eyepiece and photographic guiding. To change the speed rate of the motors:
•
Press the RATE key on the hand control. The LCD will display the current speed rate.
•
Press the number on the hand control that corresponds to the desired speed. The LCD will display "NexStar
Ready" indicating that the rate has been changed.
