Perhaps one more comment to assist you in testing your camera. Progressive scan ccds do not have a mechanical shutter. This means, the driver software must purge accumulated electrons from the ccd and its buffer before taking an actual image. In the rush for speedy images, this factor is frequently overlooked by developers seeking to have fast cameras. It is best for your testing if you loop or take a sequence of images for comparison. Thus, you may find a first, second, or even third image of a series does not appear the same as earlier images. In a similar sense be careful when making settings changes, then taking a single image. You must assure the change has occurred on a cleared ccd.
I always suggest testing in room light with a camera lens. A working QHY camera will take a very normal image, if IR filtered. Dark frames can easily be obtained with a lens cap.
