This is a side by side comparison of the color Philips ToUCam Pro II, and the monochrome TIS DMK 31AF03 with the same scope at f/41 on the same target.
Notice the difference in field of view, image scale, and cleaniness. ToUCam Pro is using USB 1.1 and DMK is using IEEE 1394. DMK has a bigger chip and thus wider field of view, DMK has smaller pixel size and thus larger image scale, DMK is cleaner both because it's monochromatic, uncompressed image, and the capability for longer exposure, also probably cleaner amplication circuit.
