CENTRALDS CDS-5D USER GUIDE
* The TEC cooling module is more efficient when the ambient temperature is high but the efficiency is
lower when the temperature is low in the winter. This is due to the electricity consumption per
temperature characteristics of the Peltier elements which is one of the most important parts in the
TEC cooling module. As a result, the cooled image sensor temperature may not reach to-38C below
ambient in the winter.
* The image sensor temperature in BackyardEOS is not the actual sensor temperature but the
temperature at the temperature sensor installed on the PCB circuit board placed 2mm behind the
sensor. Only the image sensor is directly cooled with a cold finger in the CDS-5D.
The temperature value displayed at temperature controller is from the temperature on CMOS cold
finger and it’s near to real CMOS temperature and the temperature that BackyardEOS is displaying
(from Canon exif data) is about 3-7C higher than this value.
Run the BackyardEOS program
.
16.
Close EOS Utility and click the connect button on the top left corner of BackyardEOS. This will
connect BackyardEOS and the camera.
17.
After the camera is connected to BackyardEOS, click Frame & Focus button at the center of the
button tool bar on the top left part of the program.
18.
You can check the image sensor temperature at the camera information section on the top center
area of the program.
* Please refer to the BackyardEOS User Guide.pdf for detailed usage of BackyardEOS.
19.
Close BackyardEOS and disconnect the USB cable and the power cable from the camera after
finishing the imaging session..
20.
Remove the camera from the telescope (or the camera lens).
21.
Put the lens cap on and put the camera in a case with desiccants (i.e. Silica gel).
