Utilities Menu - Celestron CGX-L Mode D'emploi

WARNING: In order for the telescope to be able to slew
to a star from the direction that minimizes the amount of
backlash in the gears, it may be necessary for the telescope
to slew beyond the specified slew limit in order to approach
the star from the correct direction. This can limit your ability
to slew to an object by as much as 6° from the R.A. slew
limit set in the hand control. If this proves to be a problem,
the direction that the telescope takes to center an object can
be changed. To change the telescopes slewing direction, see
GoTo Approach under the Scope Setup menu.
Custom Rate 9 – This allows you to customize the speed at
which the mount slews to a target You can set the R A and
Dec axes individually The max speed of the CGX-L is 4°/
second (3°/second is default)

Utilities Menu

Scrolling through the MENU (9) options will also provide
access to several advanced utility functions within the
telescope such as; Calibrate Mount, Hibernate as well as
many others
Calibrate Mount – In order to optimize the performance
and pointing accuracy of the telescope, the mount has
built-in calibration routines allowing it to compensate for
mechanical variation inherent in every German equatorial
mount Each calibration is completely automatic and in
most cases only needs to be performed once It is highly
recommended that you take a few minutes to go through
the mount calibration procedures
• 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 telescope's "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
20 | ENGLISH
Select the GoTo option to slew the telescope back to the
Home position at any time
Factory Settings – Returns the 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 relative
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 telescope 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
HINT: Pressing BACK at the Wake Up screen allows
you to explore many of the features of the hand control
without waking the telescope up from hibernate mode.
To wake up the telescope after BACK 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 To enable the Sun,
go to the Sun Menu and press ENTER The Sun will now
be displayed in the Planets catalog and can be used as an
alignment object when using the Solar System Alignment
