Image Calibration of QHY8L
Image calibration means to calibrate the CCD with
a BIAS field, a DARK field and a FLAT field. You
can completely remove thermal noise of the CCD
through proper calibration. Additionally ,you can
obtain better image highlights. You can remove
dark spots which are caused by dust on the
surface of the CCD. Image calibration is a critical
step for serious astronomical photography.
In order to obtain accurate calibration information,
you need to use the QHY8L temperature
controller. CCD should be set in
fixed temperature
state. And temperature should remain the same
when shooting .
The temperature control of EZCAP is located in
Temp Control of the menu bar of Setup. You can
stretch the temperature control section on the right
of the window of Temperature Control to set the
temperature what you want .And then select Auto

temperature for CCD. You have to wait a moment
until the temperature of CCD has been stable ,you
