zY3sp3Z6 All I see is a white image, and sometimes another single color, but never a proper image.
Reduce the exposure time and camera gain. Check the "mean ADU" in your program. If the mean ADU is over 65000, you are overexposing.
If you are testing in the daytime, use the shortest exposure time that is available to you (usually around 1ms to 32ms). And, with ZWO cameras ("gain" is in 0.1 dB), set the gain to zero.
Even that can overexpose the camera. If so, you would need some ND filters to play in the daytime.
