Select "Add a New Object". A screen will be displayed asking you to Enter R.A. and DEC
coordinates:
Enter R.A. and DEC
R.A.: 00h00m00s
DEC: +00d00m00s
You may enter the R.A. and DEC coordinates of the object you want to store, and press ENTER to
confirm.
A more useful application of this function is to store your favorite viewing objects before heading to
the field. When the "Enter R.A. and DEC" screen appears, press the MENU button. It brings up the
catalogs that you can select the object from. Follow the screen instructions to add your favorite objects.
Press BACK button to go back one level.
Press the BACK button to go back to the object entry submenu. You may review the records or
delete those that are no longer wanted. Press the BACK button to finish the operation. Now you can slew to
your favorite stars from "Custom Objects" catalog using "Select and Slew."

5.10. Zero Position

5.10.1. Goto Zero Position

This moves your telescope to its Zero Position.

5.10.2. Set Zero Position

This set the Zero Position for the firmware.
The Zero Position reference will be an undefined value after firmware upgrade, or it may lost during
power outage or HC battery replacement. You can use this function to set the zero position reference.
Press the ENTER after moving the mount to Zero Position either manually or with the hand
controller.

5.10.3. Search Zero Pos.

In the event of power failure, the mount will lose all its alignment information. This can be very
troublesome if the mount is being operated from a remote observation site and is controlled via the internet.
To counter this, the CEM70 has been equipped with a function that can find the Zero Position for an initial
mount set up.
Select "Search Zero Pos." and the mount will start to slew slowly and find the R.A. and DEC
position to set the mount to the Zero Position. When the mount has found the Zero Position, the HC will ask
if you want to calibrate the Zero Position. Press ENTER to confirm. Use the arrow keys to fine adjust the
zero position. This will correct any discrepancy in the Zero Position. Alternatively, press BACK to cancel.
