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
method To remove the Sun from displaying on the hand
control, once again select the Sun Menu from the Utilities
Menu and press ENTER
Set Mount Position
The Set Mount Position menu can be used to maintain
your alignment in cases where you wish to disengage the
clutches or similar situation For instance, you might use this
feature if you needed to rebalance the mount after having
completed an alignment To set the mount position, simply
slew to a bright star in the named star list and select Set
Mount Position The hand control will sync on the star by
asking you to center the star in the eyepiece and pressing
the Align button Once synced on the star, you are free to
manually move the mount in both axes in order to rebalance
When you are ready to slew the telescope to your next object,
just remember to manually return the tube to the same bright
star and carefully center it in the eyepiece Using this tool will
invalidate the PEC index
Turn On/Off GPS – If using your telescope with the
optional SkySync GPS accessory, you will need to turn the
GPS on the first time you use the accessory If you want to
use the telescope's database to find the coordinates of a
celestial object for a future or past dates, you will need to
turn the GPS off in order to manually enter a time other than
the present
Turn On/Off RTC – Allows you to turn off the telescope's
internal real time clock When aligning, the telescope still
receives time information from the RTC If you want to use
the hand control database to find the coordinates of a
celestial object for a future or past dates, you will need to
turn the RTC off in order to manually enter a time other than
the present
Periodic Error Correction (PEC) – PEC is designed to
improve photographic quality by reducing the amplitude of
the worm gear errors and improving the tracking accuracy of
the drive This feature is for advanced astrophotography and
is used when your telescope is accurately polar aligned For
more information on using PEC, refer to the section of the
manual on "Astroimaging "
User Objects Menu
Your telescope can store up to 400 different user-defined
objects in its memory The objects can be daytime land
objects or an interesting celestial object that you discover
that is not included in the regular database There are several
ways to save an object to memory depending on what type
of object it is:
GoTo Object: To go to any of the user defined-objects
stored in the database, scroll down to either "GoTo Sky Obj"
or "GoTo Land Obj" and enter the number of the object
you wish to select and press ENTER The telescope will
automatically retrieve and display the coordinates before
slewing to the object
Save Sky Object: Your telescope stores celestial objects
to its database by saving its right ascension and declination
coordinates in the sky This way the same object can be
found each time the telescope is aligned Once a desired
object is centered in the eyepiece, simply scroll to the "Save
Sky Obj" command and press ENTER The display will ask
you to enter a number between 1 and 200 to identify the
object Press ENTER again to save this object to the database
Save Database (Db)
• Object: This feature allows you to create your own custom
tour of database objects by allowing you to record the
current position of the telescope and save the name of the
object by selecting it from any one of the database catalogs
These objects then can be accessed by selecting GoTo
Sky Object
