Figure 6.
8408 HC LCD Information Screen
1. Target Name/Mount Position: displays the name of the target that telescope is currently pointed to or
the current mount position.
An object name, such as “Mercury” or “Andromeda Galaxy”: Name of the Star or celestial object
that the mount is currently slewing to, GOTO or tracking;
User Position: The mount is point to a user defined position, which could be a real sky object or
just simply due to press an arrow key.
2. Magnitude: the magnitude of the current celestial object
3. Right Ascension: Right Ascension of the telescope, or R.A.
4. Declination: Declination of the telescope, or DEC.
5. Azimuth: Azimuth of the telescope (north is 0º, east 90º, south 180º, and west 270º).
6. Altitude: Altitude of the telescope (degrees vertical from the local horizon - zenith is 90º).
7. Mount Status: Display current operation status of the mount.
Stop: mount is not moving;
Slew: mount is moving with an arrow key is pressed;
GoTo: mount is slewing to a celestial object using “Select and Slew”;
8. Slew speed: It has 9 speeds: 1X, 2X, 8X, 16X, 64X, 128X, 256X, 512X, MAX(1440X, or 6°/sec).
9. Current Time: display local time in a format of HH:MM:SS.
2.5. Check the Battery
The hand controller has a real time clock (RTC) which should display the correct time every time the
mount is turned on. If the time is incorrect, please check the battery inside the hand controller and
replace it if needed. The battery is a 3V, CR1220 button battery.
2.6. Bench Testing the Mount
The counterweight shaft is designed to counter balance the mount’s own weight. It is recommended
that the CW shaft is installed when testing the mount’s function.
NEVER
operate the mount with only the counterweight or OTA on it, as shown in the image in
Figure 7
.
It may cause gear slippery and cause the worm and gear damage.
