2. How to clean the CCD sensor and the optic windows of the camera?
Usually you can use flat fielding calibration to eliminate the shadow resulted from dust. It's not
recommended to open the CCD chamber to clean the CCD on your own. Because if you do it in a
place where there are still lots of dust, your effort may backfire. Besides, during the process of
cleaning, you may scratch the CCD, and you may damage the internal circuit when you open the
camera.
QHYCCD provides CCD clean service. The cleaning fee is 100 USD per time and it doesn't include
the shipping cost.
If you really want to clean it on your own, you can follow the instructions below.
