Looking for commercial CCD camears

Sure. My ordinary Sony camcorder and Canon point-and-shoot camera both use CCD sensors (not CMOS sensors).

Here are some halfway decent ones (more expensive) for amateur astronomy:

There is a few company that make CCD camera, such as Basler, Pixel-link, Sony, Firefly.... Not too sure what is your camera application(ie how you are using it, industrial, scientific or medical)?

Also you can check out the Ni website. I think they have some camera advisor stuff. Maybe you can do a search in their website

Hope it helps!
