The guide port wiring is shown in Figure 22, which has the same pin-out as that from Celestron /
Starlight Xpress / Orion Mount / Orion Autoguider/ QHY5 autoguider.
If you have an autoguider which has a pin-out the same as the ST-I from SBIG, such as Meade/
Losmandy/ Takahashi/ Vixen, make sure a proper guiding cable is used. Refer to your guiding camera and
guiding software for detailed operation.
WARNING: DO NOT plug your ST-4 guiding camera cable into the iOptron port or HBX port. It
may damage the mount or guiding camera electronics.
5.4.6. Set Tracking Rate
You can set up the mount tracking rate by selecting “Set Tracking Rate”. Then the user can select
“Sidereal Rate”, “Lunar Rate”, “Solar Rate”, “King Rate”, and “User Defined Speed”. The “User defined
speed” can be adjusted from 0.9900X to 1.0100X of sidereal.
The “King Rate”, developed by Edward S. King, corrects the tracking rate of a telescope to account
for atmospheric refraction. This is more useful for unguided tracking.
5.4.7. Meridian Treatment
This function tells the mount what to do when it tracks past the meridian. You can tell the mount if it
needs a meridian flip and when to do it.
“Set Position Limit” will tell the mount when to stop tracking or to do a meridian flip. The limit
can be set at from 0° to 10° (40 minutes) pass meridian.
“Set Behavior” will determine if the mount will stop tracking or perform a meridian flip at the set
position limit.
5.4.8. Track Below Horizon
This function allows the mount to keep tracking an object even if it is below the horizon but can still
be seen, for example from an elevated observation site, such as a hill. The power on default is Prohibited.
One can turn it on when needed.
5.4.9. Set Eyepiece Light
Use this function to adjust the light intensity of iEQ45 Pro illuminated polar scope. If you have an
illuminated-reticule eyepiece and has the same socket, you may use this option to adjust its light intensity.
5.4.10. GPS Status
Display if the GPS connection status. GPS ON indicates that the mount is still acquiring the satellite
data. GPS OK indicates the link has been established. If neither is displayed, the GPS is malfunctioning. Do
not leave the hand controller at this submenu.
5.4.11. Language
Select one of supported menu languages.
5.5. Electric Focuser
This function controls an iOptron electric focuser.
