astap program
The grid in your screenshot is caused by the different in values of the red, green and blue sensitive pixels of a single frame. The pixels are organised in a Bayer pattern. something like: rg gb In the stacked image these pixels are processed such that each four pixels are converted into a luminance and colour signal instead of four individual pixels. See: https://en.wikipedia.org/wiki/Bayer_filter cs, Han

astap program
No you should not be worried. There are some cameras which have a large difference in sensitivity for red, green or blue light. The program will compensate for it. The warning is for users where the light source is lacking one colour due to aging like for electroluminance panels. It is not for cameras with this effect. You checked the light source. If the light source is yellowish, white or light bluish your fine. You can not change your camera and the program will compensate anyhow. cs, Han
