Home Position; Light Control; Factory Settings; Version - Celestron CGEM 1100 Instruction Manual

R.A. switch - this procedure records the offset error when the right ascension index mark is aligned at start-up.

Calibrating the R.A. Index will improve the accuracy of your initial star alignments when aligning the telescope
in the future.
GoTo Calibration – Goto Calibration is a useful tool when attaching heavy visual or photographic accessories

to the telescope. Goto Calibration calculates the amount of distance and time it takes for the mount to complete
its final slow goto when slewing to an object. Changing the balance of the telescope can prolong the time it
takes to complete the final slew. Goto Calibration takes into account any slight imbalances and changes the final
goto distance to compensate.
Home Position –
The telescopes "home" position is a user-definable position that is used to store the telescope when not in
use. The home position is useful when storing the telescope in a permanent observatory facility. By default the Home position
is the same as the index position used when aligning the mount.
To set the Home position for your mount simply use the arrow buttons on the hand control to move the telescope mount to the
desired position. Select the Set option and press Enter.
Select the Goto option to slew the telescope back to the Home position at any time.

Light Control

– This feature allows you to turn off both the red key pad light and LCD display for daytime use to conserve
power and to help preserve your night vision.

Factory Settings

– Returns the telecope's hand control to its original factory settings. Parameters such as backlash
compensation values, initial date and time, longitude/latitude along with slew and filter limits will be reset. However, stored
parameters such as user defined objects will remain saved even when Factory Settings is selected. The hand control will ask
you to press the "0" key before returning to the factory default setting.

Version

- Selecting this option will allow you to see the current version number of the hand control and motor control The
first set of numbers indicate the hand control software version. For the motor control, the hand control will display two sets of
numbers; the first numbers are for azimuth and the second set are for altitude.

Get Axis Position

- Displays the relative altitude and azimuth for the current position of the telescope.

Goto Axis Position

- Allows you to enter a specific altitude and azimuth position and slew to it.

Hibernate

- Hibernate allows the telescope to be completely powered down and still retain its alignment when turned back
on. This not only saves power, but is ideal for those that have their telescopes permanently mounted or leave their telescope
in one location for long periods of time. To place your telescope in Hibernate mode:
1. Select Hibernate from the Utility Menu.
2. Move the telescope to a desire position and press ENTER.
3. Power off the telescope. Remember to never move your telescope manually while in Hibernate mode.
Once the telescope is powered on again the display will read Wake Up. After pressing Enter you have the option of scrolling
through the time/site information to confirm the current setting. Press ENTER to wake up the telescope.

without waking the telescope up from hibernate mode. To wake up the telescope after UNDO has been
pressed, select Hibernate from the Utility menu and press ENTER. Do not use the direction buttons to move
the telescope while in hibernate mode.

Sun Menu

For safety purposes the Sun will not be displayed as a database object unless it is first enabled. The enable the Sun, go to the
Sun Menu and press ENTER. The Sun will now be displayed in the Planets catalog as can be used as an alignment object
when using the Solar System Alignment method. To remove the Sun from displaying on the hand control, once again select
the Sun Menu from the Utilities Menu and press ENTER.
