6.8. Set Up Tracking
A user can set up tracking in the main menu
by selecting “Set up tracking”. Then the user
can select “Sidereal speed”, “Solar speed”,
“Lunar speed”, and “User defined speed”.
For “User defined speed” this can be
adjusted from 91% to 109% of sidereal
speed by pressing the ▲or ▼ buttons.
6.9. User Objects
Besides various star lists available in the
hand controller --you can add, edit or delete
your own user-defined objects. All data you
enter is supposedly J2000.0 epoch.
6.10. Auto Guide
This is an advanced function for autoguiding
when a guiding scopes and a camera are
equipped. The GOTONOVA supports
autoguiding through ASCOM protocol, such
as PHD Guiding or Guidedog, or an ST-4
guiding camera (an extra ST-4 to HBX
adapter is needed). Please follow the
guiding software for detailed instructions.
This function is not supported in Alt/Azi
mode.
6.11. Park Scope
This procedure only needs to be done if you
do not move your telescope mount after you
power off the GOTONOVA. Celestial pole
pointing error will be stored to flash memory
and recalled when you power on again.
6.12. To Park Position
This moves your telescope to park position.
When power is turned on--the mount
assumes the physical position is the park
position. This is its reference point for all
other objects.
7. Maintenance and
Servicing
7.1. Maintenance
The MiniTower Pro is designed to be
maintenance free. Do not overload the
mount. Do not drop the mount which will
damage the mount or affect the GOTO
tracking accuracy permanently. Use a wet
cloth to clean the mount and hand
controller. Do not use solvent.
If your mount is not to be used for an
extended period, dismount the OTAs and
counterweight. Remove the batteries from
the battery holder if they were installed.
7.2. Troubleshooting
The following suggestions may be helpful
for the operation of the MiniTower Pro. More
information can be found in our online FAQ
section (
www.iOptron.com then click on
“support”).
1. Error Message “Warning! DEC. (or
R.A.) driver motor over current. Please
check balance.”
(1) Check if the mount or OTA is blocked
by any obstructions.
(2) Try to operate the mount without an
OTA.
(3) Check the power supply. This is a
common reason for this message and
unexpected slew behavior or movement
.
which include:
• Batteries: Are the batteries fresh? How
long have they been used? (frequent
slewing and GOTO will deplete battery
power very quickly)
• AC or DC adapter: Check the plugs to
the mount and to the power outlet.
• Extension cord: Make sure the cord is in
good condition. Power drop along the
extension cord has been known to
cause this error message. Also check all
the plugs and connections.
