Is it possible to use QHY5 for daytime observation ? IN other words imaging in bright day light ? I have tried tuning various parameters with PHD but am failing to get any image .... can any one help with what exact parameters should be tuned... Taking in mind that i tried QGVideo and it is working and managed in getting video... Appreciate your help. Thank you.

This way i have managed to get images during daylight.

Exposing at even the fastest speed available will be too slow and the camera will be saturated in daylight conditions.

Turning down the gain won't help if the CCD wells are full. The image will just look uniform gray instead of white.
