« on: April 30, 2020, 03:55:49 PM »
photographs with my QHY168C camera have gradients. Generally the left side of the frame and the top and bottom edges look brighter. This also happens with dark frames but they are not minimized in the image post processing (they seem to increase)
In darks frames  the average value for 30 s exposure is 39 ADU in the lower left corner of the image, while in the center of the right edge it is 32 ADU. This is systematic and the values are proportionally higher for higher exposures.
Could this be because the anti-amp light control function is not working (or it is incorrectly configured)?
Can someone help me solve the problem?
