This is an unmodified usb Philips ToUcam Pro II USB web cam. It is in as new condition in it’s original box with the original software and instruction booklet. The camera was only used a few times as a web cam and put back in it's box. I believe this is one of the best web cams to modify for Astrophotography. If you have any questions abou the camera then please email me.
