iOptron 7200, 7201 instruction manual Electric Focuser

The guide port wiring is shown in Figure 26, which is same as that from Celestron / Starlight Xpress / Orion Mount / Orion Autoguider/ QHY5 autoguider pinout.

If you have an autoguider that has a pinout similar to ST-i of 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.

DO NOT plug your ST-4 guiding camera cable into any iOptron port or HBX port. It may damage the mount or guiding camera electronics.

5.4.5. Set Tracking Rate

You can set up the mount tracking rate by selecting “Set Tracking Rate”. Then the user can select “Sidereal speed”, “Lunar speed”, “Solar speed”, “King speed” and “User defined speed”. For “User defined speed,” it can be adjusted from 0.9900X to 1.0100X of sidereal speed by pressing the ▲or ▼ button or the number buttons.

5.4.6. Set Parking Position

You may park the telescope before powering off the mount. This is very useful if the mount is on a permanent pier or the mount will not be moved in between observation sessions. The mount will keep all the alignment info and reference points.

There are four parking positions. “Default Horizon Pos.” will park the scope horizontally on the right side of the mount. “Default Zenith Pos.” will park the scope vertically on the right side of the mount. “Current Position” will park the scope at its current position. Or you can enter any altitude and azimuth combination for “Custom Parking Pos.” When the mount is turned on, it will use last time parking position setting as the default setting.

5.4.7. Meridian Treatment

This function tells the mount what to do when it tracks past the meridian. There are two options. Telescope Flip will flip the telescope and continuously track the object. Stop Tracking Pos. will stop the mount when it passes the meridian. You can define how far the mount will track pass the meridian before it stops. The maximum traveling distance is 15°passing meridian, which equals to 1 hour.

5.4.8. Track Below Horizon

This function allows the mount to keep tracking an object even it is below the horizon but still can be seen from an elevated observation site, such as on a hill. The power on default is at OFF state. One can turn it on when needed.

5.4.9. Set Eyepiece Light

Use this function to adjust the light intensity of a CEM60 illuminated polar scope. If you have an illuminated-reticule eyepiece and has the same socket size, you may use this option to adjust its light intensity.

5.4.10. Heating Controller

Turn on/off the controller LCD back heater. When select ON for “Heating Controller”, the heater would automatically be turned on when the ambient temperature reached 0°C (32°F) and shut off at 10°C.

5.5. Electric Focuser

This function controls iOptron electric focuser.
