Drying the CCD Chamber
The CCD sensor is located in a CCD chamber. This chamber is air-proof and connect to the socket
of the silicone gel tube on one side of the QHY183C front case. If there is moisture and cause the
CCD sensor glass get dew. You can connect the silicone gel tube on the socket to dry it.
Please put the effective silicone gel into the silicone gel tube. Make sure this is a cotton inside to
prevent the silicone gel get into the CCD chamber.
Avoid CCD chamber optic window get dew
If the environment humidity very high, the optic window of the CCD chamber may get dew. The
QHY183C has the build-in heat board on this optic window to heat the optic window to avoid it.
In most conditions it can take effect.
If the optic window still get dew please try the following method.
1. Avoid the CCD Camera face down to ground. The cold air is heavy than warm air, if you put the
camera facing down to the ground, the cold air is easy to get the optic window and cause it very
cold and get dew
2. Increase the temperature of the CCD sensor. You can increase the CCD sensor temperature a
little to prevent the optic window get dew.
3. Check if the heat board working. If the heat board not working, the optic window is easy to get
dew. Normally the heat board can get about 65-70C in +25C environment. If it is not so warm, it
maybe the problem of the heat board damaged. Need to contact QHYCCD to replace one heat
board.
