  • Page 17: Peripheral Ports On Qhy90A

    Keep the camera in good contact with the earth is the premise that the entire shooting system can work safely and properly. So QHY90A provides a grounding port. This port is connected to the GND on the PCB in the camera, and the GND is also the cathode of the 12V power supply. The grounding wire is included in the package, you can use it to connect the camera to other equipment (Metal case of the equatorial mount or metal case of PC) so that they have common ground.
  • Page 18 Caution: Never connect the grounding port to any electrical socket or outlet, otherwise, electrical shock may happen. Note that the camera used in the picture above isn’t QHY90A, it is QHY16803A. They have the same peripheral ports. 12V power ports These two ports are connected in parallel, so you can either one of these two as power input port and use the other one as a power output port for other devices that need 12V power supply.

  • Page 23 5. How to protect the cooler in QHY90A? The cooler in QHY90A can lower the CCD temperature to a value that's almost 40 degrees centigrade below the ambient temperature. So you need to be careful to avoid thermal shock, which refers to when the cooler's temperature rises or fall dramatically, the cooler is subjected to strong internal stress due to contraction principle.
